The US says it was behind a drone strike in Iraq's capital Baghdad that killed two commanders of Kataib Hezbollah, an Iran-backed militia group linked to the killing of three US troops last month.

This article introduces an experimental emulation of a novel chunk-based flexible multi-DoF aerial 3D printing framework. The experimental demonstration of the overall autonomy focuses on precise motion planning and task allocation for a UAV, traversing through a series of planned space-filling paths involved in the aerial 3D printing process without physically depositing the overlaying material. The flexible multi-DoF aerial 3D printing is a newly developed framework and has the potential to strategically distribute the envisioned 3D model to be printed into small, manageable chunks suitable for distributed 3D printing. Moreover, by harnessing the dexterous flexibility due to the 6 DoF motion of UAV, the framework enables the provision of integrating the overall autonomy stack, potentially opening up an entirely new frontier in additive manufacturing. However, it's essential to note that the feasibility of this pioneering concept is still in its very early stage of development, which yet needs to be experimentally verified. Towards this direction, experimental emulation serves as the crucial stepping stone, providing a pseudo mockup scenario by virtual material deposition, helping to identify technological gaps from simulation to reality. Experimental emulation results, supported by critical analysis and discussion, lay the foundation for addressing the technological and research challenges to significantly push the boundaries of the state-of-the-art 3D printing mechanism.

US Central Command (Centcom) confirmed that the attack had been carried out at 21:30 local time (18:30GMT), and had killed the "commander responsible for directly planning and participating in attacks on US forces in the region".

A senior commander from Kataib Hezbollah, an Iran-backed armed group in Iraq that the Pentagon linked to an attack that killed three US troops, died in a drone strike on a vehicle in eastern Baghdad, according to security sources and media reports. One of the sources said three people were killed and that the vehicle targeted on Wednesday night was used by Iraq's Popular Mobilisation Forces (PMF), a state security agency composed of dozens of armed groups, many of them close to Iran. Two officials with Iran-backed armed groups in Iraq said that senior commander Abu Baqir al-Saadi was among those killed, the Associated Press news agency reported. Local outlet Sabereen News also reported al-Saadi had been killed in the blast. Al Jazeera's Ali Hashem, reporting from Baghdad, said that "several explosions" were heard across the Iraqi capital and that security sources said three people have been killed.

Fox News chief national security correspondent Jennifer Griffin has the latest on the strike on'The Story.' The U.S. carried out a drone strike in Baghdad late Wednesday that killed three members of the powerful Kataib Hezbollah militia – including a high-ranking commander connected with a drone strike that killed three U.S. troops in Jordan late last month. U.S. Central Command (CENTCOM) said forces conducted a unilateral strike in Iraq around 9:30 p.m. in response to a drone strike that killed three U.S. troops in Jordan on Jan. 28. The strike, which occurred on a main thoroughfare in Baghdad's Mashtal neighborhood, was considered a "high-value individual target," Fox News is told. People inspect the vehicle targeted by airstrike in Baghdad, Iraq on February 07, 2024.

A Pennsylvania man could face up to four years in prison after he was charged in a federal criminal complaint for illegally flying a drone over the Baltimore Ravens stadium during the AFC Championship last month, causing an unusual delay of game. The U.S. Attorney's Office for the District of Maryland announced the charges on Monday, alleging that Matthew Hebert, 44, violated a temporary flight restriction placed on M&T Bank Stadium when he flew a drone over the area during the NFL game. Zay Flowers of the Ravens makes a catch for touchdown during the AFC Championship game against the Kansas City Chiefs at M&T Bank Stadium on Jan. 28, 2024, in Baltimore.

Houthi militants in Yemen are using Iranian-supplied missiles and drones to attack civilian and military targets across the Middle East, analysis from the Defense Intelligence Agency (DIA) shows. The report, "Iran: Enabling Houthi Attacks Across the Middle East," aims to provide more insight into the relationship between Iran and the Houthis. The militant group, stationed in Yemen, has for months been striking commercial vessels traveling through the Red Sea in protest of Palestinian civilians killed during Israel's ongoing offensive against Hamas members in Gaza. Houthi fighters stage a rally in support of the Palestinians in the Gaza Strip and against the U.S.-led airstrikes on Yemen, in Sanaa, Yemen, Monday, Jan. 29, 2024. Most recently, Houthi rebels fired ballistic missiles at two ships traveling through Middle East waters.

Ukraine's commander-in-chief has outlined a plan to massively scale up the use of unmanned systems to overcome Russia's advantages in manpower and materiel and break the deadlock in this war. The effectiveness of such systems was proved again last week as they sank a Russian missile corvette, grounded three planes and set an oil refinery on fire. Russia, too, continued to attack Ukraine with drones and missiles, but it failed to capture new territory despite its superior resources and constant assaults on the eastern city of Avdiivka and Ukraine's stronghold at Krynky on the left bank of the Dnipro River in the Kherson region. Meanwhile, Ukraine's Western allies made progress on securing funding for the war. The European Union finally approved a 50-billion-euro ( 63bn) aid package for Ukraine, and the United States Senate unveiled a 118bn bill that includes 60bn for Ukraine.

Russia's Black Sea Fleet suffered significant losses over the five months following the collapse of the U.N.-brokered grain deal as Ukraine staked a strong claim over major routes through the Black Sea. Russia's Black Sea fleet has suffered severe setbacks as Ukrainian forces continue to cripple a major piece of Moscow's war effort. Last week, Ukrainian media touted a major victory over the Russian fleet with the publication of a video that allegedly showed the destruction of a nearly 70 million missile ship, the Ivanovets. Multiple drones hit the vessel and sank it, with the crew's fate unknown. "As a result of a number of direct hits to the hull, the Russian ship received damage that was incompatible with further movement – the Ivanovets tilted to the stern and sank," said the Military Informant Telegram channel.

Russia fired cruise and ballistic missiles and Shahed-type drones at targets across Ukraine, killing at least three civilians and injuring more than 10 people, Ukrainian authorities said. Russia targeted at least three big cities, according to the Ukrainian military, which said it intercepted 44 drones and missiles of the 64 that were launched. President Volodymyr Zelenskyy said two people were killed in the capital, Kyiv, and one person in Mykolaiv in the south of the country. Six regions were under the enemy's strike. All our services are now working to cope with the consequences of this terror," he posted on X. Six regions came under enemy fire.
