Al-Majalah camp attack

The al-Majalah camp attack occurred on December 17, 2009, United States fired Tomahawk cruise missiles at an alleged training camp in Al-Majalah, Abyan, killing 24–50, including 14 women and 21 children.

Background
Since 2006, al-Qaeda had managed to regroup and grow stronger as Yemen's government struggles to hold on to its territory amid multiple rebellions and rising poverty.

The attack
The al-Majalah camp attack took place on December 17, 2009, when Yemeni ground forces attacked an alleged training camp in Al-Majalah, Abyan, killing 24–50, including 14 women and 21 children. Yemeni forces also carried out raids in Sana'a (arresting 13) and Arhab (killing 4 and arresting 4).

US involvement
According to ABC News, American cruise missiles were also part of the raids. The U.S. denied they were involved in the strikes, despite accusations from Amnesty International.

Aftermath
A primary target in the attacks — Qasim al-Raymi, the al-Qaeda leader who was believed to be behind a 2007 bombing in central Yemen, that killed seven Spanish tourists and two Yemenis — survived the attack.

Reports of a U.S. role, and mass civilian casualties at the sites of the attacks, have sparked a public outcry and added to anti-American sentiments across the country.
