WASHINGTON U.S. missile strikes, including armed drone attacks, have killed dozens of civilians in Yemen as the United States tries to crack down on al Qaeda in the country, a prominent human rights organization said on Tuesday.
Human Rights Watch detailed in a 96-page report what it said were six "unacknowledged" U.S. military attacks on targets in Yemen, which either clearly, or possibly, violated international law.
Eighty-two people, 57 of whom were civilians, were killed during the six attacks studied by the group. One of the incidents occurred in 2009 and the other five happened in 2012-2013.
The Human Rights Watch report is being released at the same time as Amnesty International is issuing a report on U.S. drone strikes in Pakistan.
Two strikes in Yemen - one in September 2012 and the other in December, 2009 - caused what Human Rights Watch said were the largest numbers of civilian casualties.
On September 2, 2012, as two U.S. drones flew above the target area, either two additional drones or two warplanes attacked a vehicle traveling north from the central Yemeni city of Radaa.
That attack killed 12 passengers in the vehicle, including three children and a pregnant woman, in violation of a law of war prohibiting attacks that do not discriminate between civilians and combatants, Human Rights Watch said.
The group said the apparent target of the raid was a tribal leader named Abd al-Raouf al-Dahab. He was not in the vehicle when it was attacked and that it was not clear that he was a member of al Qaeda's Yemeni affiliate, known as al Qaeda in the Arabian Peninsula.
Of the six cases it studied, Human Rights Watch said at least four of the strikes were carried out by missile-firing drones. A fifth was carried out either by drones or airplanes, and the sixth by cruise missiles that the group said released cluster bombs.
In December 17, 2009, an attack by as many as five U.S. Navy cruise missiles struck a Yemeni hamlet, killing what the Yemeni government initially described as 34 "terrorists" at a training camp.
However, Human Rights Watch said a Yemeni government inquiry later established that although 14 fighters for al Qaeda's Yemeni affiliate were killed in the attack, so were at least 41 civilians, including nine women and 21 children.
