Islamabad, June 12 (RHC)-- The U.S. has resumed its drone war in Pakistan after a nearly six-month pause. At least 14 people have been killed in two strikes on Wednesday, making it the first known U.S. drone attack in Pakistan since December.

The drone strikes come days after Taliban fighters stormed the Karachi airport, leaving 36 dead, including the 10 attackers. The strikes on Wednesday come despite the Pakistani government’s repeated calls on the United States to end the attacks.

Washington claims its drone strikes target militants, although casualty figures clearly indicate that Pakistani civilians are the main victims of the non-UN-sanctioned attacks.

The slaughter of Pakistani civilians, including women and children as a result of U.S. drone strikes has strained ties between Islamabad and Washington, and Pakistani officials have complained to the U.S. administration on numerous occasion.

United Nations and several human rights organizations have identified the U.S. as the world's number one user of "targeted killings," largely due to its drone attacks in Pakistan and Afghanistan.
