President Joe Biden announced Feb. 4 the United States will end support for the Saudi-led military campaign in Yemen that has deepened suffering in the Arabian Peninsula's poorest country. "This war has to end," Biden told diplomats in his first visit to the State Department as president, saying the conflict has created a "humanitarian and strategic catastrophe." Biden pledged an end to "relevant" US arms sales, while giving no immediate details on what that would mean. The administration had already said it is pausing some of the billions of dollars in arms deals with Saudi Arabia and the United Arab Emirates.

Over the past weeks, the two biggest members of the international coalition supporting the official government of Yemen against the Houthi rebels have fallen out, with Saudi Arabia continuing to back President Abd-Rabbu Mansour Hadi and the United Arab Emirates switching its support to southern separatists. Last week, the UAE-backed Security Belt militia, armed wing of the Southern Transitional Council (STC), seized effective control of the port city of Aden after days of fighting with Saudi-backed forces of the official government.

US warplanes and drones struck supposed al-Qaeda targets in Yemen for a second straight day March 3, killing at least 12 suspected militants, according to local officials. The Pentagon said it had carried out more than 20 strikes overnight targeting al-Qaeda positions in the southern provinces of Shabwa and Abyan, and the central province of Baida. In the latest strikes, US fighter jets hit three houses in the Yashbam Valley before dawn, one of them reportedly the home of al-Qaeda's Shabwa province commander, Saad Atef, local sources said. Tribal sources said that several civilians were wounded, including women and children. One resident said it had been a "terrifying night." (Middle East Online, Al Jazeera, BBC News)

President Trump's first commando raid left dead the US-born 8-year-old daughter of Anwar al-Awlaki, the American al-Qaeda leader who was himself killed in a US strike five years ago. US special operations forces on Jan. 30 targeted the home of Abdulrauf al-Dhahab, said to be a leader of al-Qaeda in the Arabian Peninsula (AQAP), in the remote Yemeni district of Yakla. The district is in the central province of al-Baydah, a focal point of US military operations over the past month. The Pentagon said 14 AQAP fighters were killed in the raid, as well as one soldier—said by media accounts to have been a member of SEAL Team 6. Warplanes struck Abdulrauf's home; then US troops descended from helicopters and clashed with local fighters. US helicopters destroyed other homes in the area as fighting intensified.

It requires a really special kind of cynicism to pull this one off—the kind born of complete impunity, when the world gives you a blank check to carry out any kind of atrocity. Saudi fighter jets on Aug. 21 carried out air-strikes on a peaceful rally in Yemen's capital Sanaa that had been called to protest Saudi air-strikes. Most recent accounts put the death toll at three, but it seems very likely to rise. The protesters were mostly armed, and began firing on the warplanes with their AK-47s after the air-strikes, in a useless act of defiance. The rally was called after Doctors Without Borders (MSF) withdrew its staff from six Yemen hospitals in response to a Saudi sir-strike on a hospital that left 19 people dead in the northern province of Hajja. It was the fourth health facility supported by MSF to be hit by Saudi-led coalition air-strikes over the course of the war, now in its 17th month. The US continues to have military advisors directly supporting the Saudis' air war in Yemen. This week, their number was cut from about 45 to five, although US officials said this was not due to concern over civilian casualties.

The US military killed "dozens" of AQAP fighters in an air-strike that targeted a training camp in western Yemen March 22. The Pentagon claims that the strike—on a camp in Hajr, in mountains west of the port city of Mukallah—will deny AQAP "safe haven," but the air campaign waged by the US against the al-Qaeda franchise since 2009 has done little to halt its advance. Since launching an offensive last year, AQAP has gained control of at least eight cities and towns in Yemen, including the provincial capitals of Hadramout (Mukallah), Abyan (Zinjibar) and Lahj (Houta).

US President Barack Obama delivered his plan to close Guantánamo Bay (PDF) to Congress on Feb. 23. This plan comes seven years after Obama first announced he planned to shut down the prison by the end of his presidency. Under the proposed plan, detainees not fit for US prosecution or deportation would be transferred to a yet-undisclosed detention facility in the US. The plan also prioritizes transferring detainees to their home countries when possible, or resettlement in third countries. The plan states that "closing the Guantánamo Bay detention facility is a national security imperative. Its continued operation weakens our national security by furthering the recruiting propaganda of violent extremists, hindering relations with key allies and partners, and draining Department of Defense resources."

Human Rights Watch is calling on the Obama administration to cancel a pending arms sale to Saudi Arabia in the absence of serious investigations into alleged laws-of-war violations in Yemen. On No. 17, the Pentagon announced that the State Department had approved a sale of $1.29 billion worth of air-to-ground munitions such as laser-guided bombs and "general purpose" bombs with guidance systems. "The purchase replenishes the Royal Saudi Air Force's current weapons supplies, which are becoming depleted due to the high operational tempo in multiple counter-terrorism operations," the Pentagon statement said. But HRW's Joe Stork countered: "The US government is well aware of the Saudi-led coalition's indiscriminate air attacks that have killed hundreds of civilians in Yemen since March. Providing the Saudis with more bombs under these circumstances is a recipe for greater civilian deaths, for which the US will be partially responsible."
