UNITED NATIONS - Secretary-General Ban Ki-moon has reminded the United States that the use of armed unmanned aerial vehicles (UAVs) for targeted attacks was bound by international law, according to his spokesman.

Deputy Spokesman Eduardo del Buey was responding to a statement made by a UN expert investigating casualties from the US drone strikes in Pakistan declaring the attacks violate the country’s sovereignty.

“The Secretary-General remains concerned by the use of UAVs for targeted attacks,” Spokesman del Buey said when asked for comments by Ben Emmerson, the UN special rapporteur on human rights and counter-terrorism, that the Pakistani government made clear to him that it does not consent to the strikes.

Reacting to Emmerson’s statement, the UN spokesman said “The use of unarmed UAVs is subject to long-standing rules of international law, especially international humanitarian law. There is a need for greater international confidence in the international community that the use of these weapons is within the bounds of international law.”
