If you look at the record, America has been concerned about not alienating Pakistan for the last 10 years or more. But the Afghans are clear about this, and the Americans know that one of the reasons the Taliban insurgency has been resilient is that they have sanctuaries across the border in Pakistan, in Balochistan. I think the Americans were thinking that Pakistan would probably deliver the Taliban, because they had influence over them. Pakistan claims they have control, but then they say, "well, we don't have full control, we can bring them to the table but we can't make them do things unless you promise something concrete."

SeaDrone, the underwater robot coming out of a new company founded by two Stanford AI lab veterans, is aiming to make fish farming a lot easier--particularly for smaller aquaculture operations--by making underwater inspection cheaper and easier. The ocean ROV's story is not an unusual one for Silicon Valley: two Stanford students meet over a lab bench, get an idea that something they'd been tinkering around with for themselves could be turned into a product and the basis of a company. It's a story Silicon Valley loves. Eduardo Moreno met Shuyun Chung in the Stanford AI lab in 2013. Moreno, in the thick of his studies for a master's degree in mechanical engineering, was working on underwater robot hardware in collaboration with King Abdullah University of Science and Technology in Saudi Arabia.

HARI SREENIVASAN: The man who led the Afghan Taliban for the past year was killed in a U.S. operation over the weekend. The group had been gaining ground and waging a bloody war against the Afghan government. So, what's next for the Taliban, and the countries who fight it? Chief foreign affairs correspondent Margaret Warner begins our coverage. MARGARET WARNER: Smoldering wreckage on a Pakistani roadside was all that remained of the Taliban commander's vehicle hours after he died in it Saturday.

Passengers on a 14-day cruise were treated to an unusual sight in Shark Bay, Australia - about 70 tiger sharks feeding on a dead whale. Tour group Eco Abrolhos told the BBC the humpback whale had died naturally. It said the sight was "something to tell the grandchildren".

Al Qaeda has returned to its longtime base of operations in southern Afghanistan and is plotting new attacks against the West, fifteen years after being overrun by U.S.-led NATO forces following the 9/11 attacks, according to a published report. Britain's Daily Telegraph, citing Afghan security officials, reported Monday that Al Qaeda cells have moved back into southern Afghanistan following the withdrawal of most U.S. and allied troops in 2014. The report claimed that most of the cells are operating around the southern Afghan city of Kandahar, the spiritual home of the Taliban. The Telegraph reports that security officials believe that Al Qaeda's return to Afghanistan is the latest move to re-establish its strength after the killing of Usama bin Laden by Navy SEALs in 2011 and the rise of ISIS, a former Al Qaeda splinter group. The report comes days after a U.S. drone strike killed Afghan Taliban leader Mullah Mohammed Akhtar Mansour.

A U.S. drone strike targeting the Afghan Taliban's commander, Mullah Akhtar Mansour, led to the leadership council meeting Sunday to discuss succession, two Taliban sources told Reuters. This has been the strongest indication by the group of its acceptance of Mansour's death. Pakistani local residents gather around a destroyed vehicle hit by a drone strike, in which Afghan Taliban Chief Mullah Akhtar Mansour was believed to be travelling, in the remote town of Ahmad Wal in Balochistan, around 100 miles west of Quetta, May 21, 2016. President Barack Obama, according to ABC, has released a statement confirming Mansour's death. In the statement, Obama called Mansour's death "an important milestone in our longstanding effort to bring peace and prosperity to Afghanistan."

This photo taken by freelance photographer Abdul Malik on Saturday, May 21, 2016, purports to show volunteers standing near the wreckage of the destroyed vehicle, in which Mullah Mohammad Akhtar Mansour was allegedly traveling in the Ahmed Wal area in Baluchistan province of Pakistan, near Afghanistan border. A senior commander of the Afghan Taliban confirmed on Sunday that the extremist group's leader, Mullah Mohammad Akhtar Mansour, has been killed in a U.S. drone strike.

Balochistan, PAKISTAN/KABUL/WASHINGTON – Taliban supremo Mullah Akhtar Mansour was killed in a U.S. drone attack in Pakistan, senior militant sources told AFP Sunday, adding that an insurgent assembly was underway to decide on his successor. Saturday's bombing raid, the first known U.S. assault on a top Afghan Taliban leader on Pakistani soil, marks a major blow to the militant movement, which saw a new resurgence under Mansour. The elimination of Mansour, who rose to the rank of leader nine months earlier after a bitter internal leadership struggle, could also scupper any immediate prospect of peace talks. "I can say with good authority that Mullah Mansour is no more," a senior Taliban source told AFP. Mansour's death, which risks igniting new succession battles within the fractious group, was confirmed by two other senior figures who said its top leaders were gathering in Quetta to name their future chief.

Drone use across the U.S. is soaring, and the skies may soon get even more crowded, as the Federal Aviation Administration expects sales of these unmanned aerial vehicles to jump to seven million in 2020 from about 2.5 million this year. Interest in drones for both commercial and casual purposes is raising not only safety and privacy concerns, but also thorny legal questions about where and when drones should be allowed to fly--and who gets to decide. On one side are those who say property owners' rights generally extend up about 500 feet, which gives them the right to prevent drones from flying or hovering over their land. They say drones pose a much bigger threat to security and privacy than jets and airplanes, which travel at higher altitudes, in airspace regulated by the FAA. They say drones represent the next frontier in aviation, and as such, decisions about where and when they can fly should be made collectively, not by landowners through tort law.

ALISON STEWART, PBS NEWSHOUR WEEKEND ANCHOR: Joining me now via Skype to discuss the significance of the U.S. military strike on the Taliban's leader is Jennifer Glasse, a freelance reporter, now in Afghanistan's capital, Kabul.
