At least seven people have been killed in an airstrike carried out by a US killer drone in southern Yemen.
The raid took place on Saturday after the US drone fired missiles at two vehicles in Abyan Province.
Several others were also reportedly injured in the attack.
On May 20, two people were killed in a similar airstrike in the central province of Bayda.
On May 18, a US drone targeted a truck in the al-Mahfad region of Abyan Province, killing four people.
Five people were also killed in two similar strikes in a mountainous area near Sana’a on May 16.
The United States has stepped up its killer drone operations in Yemen over the past few years.
Washington has come under fire for increasing the drone attacks in Yemen, where the people have held many demonstrations to condemn the violation of Yemen’s sovereignty.
According to the Washington-based think tank, the New America Foundation, the US drone attacks in Yemen almost tripled in 2012, surging from 18 to 53.
US officials claim that the airstrikes target militants, but local sources say civilians have been the main victims of the attacks.
