Ayman al-Zawahri, Top Qaeda Leader, Killed in U.S. Drone Strike
In his short address, delivered on a White House balcony with the monuments behind him, the president vowed not to permit another sanctuary for terrorism. "We will never again, never again allow Afghanistan to become a terrorist safe haven, because he is gone and we're going to make sure nothing else happens," he said. "It can't be a launching pad against the United States. We're going to see to it that won't happen." While celebrating al-Zawahri's killing, Republicans wasted little time on Monday night asserting that the president's withdrawal had endangered the country.
Al-Qaida leader's killing highlights Afghanistan's renewed role as terrorist haven
The death of al-Qaida leader Ayman al-Zawahri in a U.S. drone strike in Afghanistan over the weekend marks the biggest blow to the terrorist group since the killing of Osama bin Laden in 2011. At the same time, it highlights the extent to which members of the jihadi organization seem to once again be operating freely in the Taliban-ruled country following the withdrawal of U.S. and coalition troops last August.

US Kills Al-Qaeda Chief In Kabul Drone Strike
A United States drone strike killed Al Qaeda chief Ayman al-Zawahiri at a hideout in the Afghan capital, President Joe Biden said Monday, adding "justice had been delivered" to the families of the September 11, 2001 attacks. In a somber televised address, Biden said he gave the final go-ahead for the high-precision strike that successfully targeted Zawahiri in the Afghan capital over the weekend. "Justice has been delivered and this terrorist leader is no more," Biden said, adding that he hoped Zawahiri's death would bring "closure" to families of the 3,000 people killed in the United States on 9/11. A senior administration official said Zawahiri was on the balcony of a house in Kabul when he was targeted with two Hellfire missiles, an hour after sunrise on July 31, and that there had been no US boots on the ground in Afghanistan. "We are not aware of him ever leaving the safe house. We identified Zawahiri on multiple occasions for sustained periods of time on the balcony of where he was ultimately struck," the official said.
US killing al-Zawahiri in Kabul a violation of Doha pact: Taliban
The Taliban has condemned the killing of al-Qaeda leader Ayman al-Zawahiri by the United States in a "precision" drone strike in the centre of Kabul. The killing of al-Zawahiri, an Egyptian surgeon who had a $25m bounty on his head for the September 11, 2001 attacks, is the biggest blow to the armed group since its founder Osama bin Laden was killed in 2011. In a statement on Tuesday, the group called the strike a "clear violation" of international principles and the Doha Agreement, the 2020 pact signed by the Taliban and the US that facilitated the withdrawal of international forces from Afghanistan. The strike was carried out on a residential house in the Sherpur area of Kabul, a diplomatic enclave where many Taliban leaders live now, Taliban chief spokesperson Zabihullah Mujahid said in the statement. "Such actions are a repetition of the failed experiences of the past 20 years and are against the interests of the US, Afghanistan and the region," Mujahid said.
EXPLAINER: Who was al-Zawahri -- and why did US kill him?
A U.S. drone strike in Afghanistan this weekend killed Ayman al-Zawahri, who helped Osama bin Laden plot the Sept. 11, 2001, attacks on the United States and ensured al-Qaida survived and spread in the years after. President Joe Biden on Monday announced the killing of al-Zawahri, delivering a significant counterterrorism win just 11 months after American troops left the country. A look at the al-Qaida leader, who evaded U.S. capture for 21 years after the suicide airliner attacks that in many ways changed America and its relations with the rest of the world. Americans who lived through the 9/11 attacks may not remember al-Zawahri's name, but many know his face more than two decades on: a man in glasses, slightly smiling, invariably shown in photos by the side of bin Laden as the two arranged the strike on the United States. An Egyptian, al-Zawahri was born June 19, 1951, to a comfortable family in a leafy, drowsy Cairo suburb.
The Strike That Killed al-Qaida's Ayman al-Zawahiri Is a Bigger Deal Than It Sounds Like
President Joe Biden's surprise announcement Monday night--that a U.S. drone strike over the weekend killed Ayman al-Zawahiri, leader of al-Qaida and co-architect of the 9/11 terrorist attack--is both more and less significant than it might seem at first glance. On the one hand, mainly because of the West's counter-terrorism strategies, al-Qaida is far from the potent global force that it was a decade ago. Its presence has been muted, and Zawahiri himself has hidden so far out of sight that one prominent expert speculated back in November that he might have been killed already. On the other hand, one fact about this drone strike hints at a much larger finding: It took place in Afghanistan. It turns out Zawahiri was living with his family in a large safehouse in downtown Kabul--meaning he had to be there with the Taliban's full blessing. This means that, contrary to the Taliban's assurances, they have been plotting a revival of their alliance with al-Qaida--the alliance that Osama bin Laden formed at the turn of the century and that spawned the attack on the World Trade Center.
The Death of Ayman al-Zawahiri
In 2002, when I profiled Ayman al-Zawahiri for The New Yorker, he was called "the man behind bin Laden." But since bin Laden was killed by American special forces in 2011, Zawahiri has been Al Qaeda's leader. Zawahiri and bin Laden were very different men, not friends but allies, using each other for the skills and resources they could each provide. Al Qaeda would not have survived without the dynamic they created together. Zawahiri, reportedly killed in Afghanistan by a U.S. drone strike over the weekend, was a doctor--a highly-educated professional who chose to devote himself to violent revolution.
Biden Says US Killed Al-Qaeda Chief Al-Zawahiri In Afghanistan
President Joe Biden announced Monday that the United States had killed Al-Qaeda chief Ayman al-Zawahiri, one of the world's most wanted terrorists and suspected mastermind of the September 11, 2001 attacks. In a televised address, Biden said the strike in Kabul, Afghanistan had been carried out on Saturday. "I gave the final approval to go get him," he said, adding that there had been no civilian casualties. "Justice has been delivered and this terrorist leader is no more," Biden said. A senior administration official said Zawahiri had been killed on the balcony of a house in Kabul in a drone strike, and that there had been no US boots on the ground in Afghanistan.
Al Qaeda leader Ayman Al Zawahiri killed in drone strike: 9/11 families react
A senior administration official confirmed Zawahri's death to Fox News, saying the U.S. conducted a counterterrorism operation against "a significant al Qaeda target in Afghanistan."

"This is a significant step forward and is particularly meaningful to the 9/11 community as we continue our years-long battle for justice and accountability," 9/11 Justice said in a statement provided to Fox News Digital. "We urge President Biden to continue to stand with the 9/11 community and all those who seek justice by holding Saudi Arabia accountable for the 9/11 attacks," 9/11 Justice said.

Present and Future of SLAM in Extreme Underground Environments

This paper reports on the state of the art in underground SLAM by discussing different SLAM strategies and results across six teams that participated in the three-year-long SubT competition. In particular, the paper has four main goals. First, we review the algorithms, architectures, and systems adopted by the teams; particular emphasis is put on lidar-centric SLAM solutions (the go-to approach for virtually all teams in the competition), heterogeneous multi-robot operation (including both aerial and ground robots), and real-world underground operation (from the presence of obscurants to the need to handle tight computational constraints). We do not shy away from discussing the dirty details behind the different SubT SLAM systems, which are often omitted from technical papers. Second, we discuss the maturity of the field by highlighting what is possible with the current SLAM systems and what we believe is within reach with some good systems engineering. Third, we outline what we believe are fundamental open problems, that are likely to require further research to break through. Finally, we provide a list of open-source SLAM implementations and datasets that have been produced during the SubT challenge and related efforts, and constitute a useful resource for researchers and practitioners.
