The US carried out its first drone strike in Pakistan in 2004 and has carried out nearly 350 more since then, the majority of which have been in North Waziristan. President Barack Obama significantly ramped up attacks when he took office in 2009, and the number peaked the following year with over 100 strikes. The frequency has steadily dropped since then, partly because of growing tension between Pakistan and the US. There have only been around two dozen strikes so far this year.
Pakistani officials regularly denounce the attacks in public as a violation of the country's sovereignty, but senior members of the government and the military are known to have supported the strikes in the past.
"Amnesty International is also extremely concerned about the failure of the Pakistani authorities to protect and enforce the rights of victims of drone strikes,'' said the report. "Pakistan has a duty to independently and impartially investigate all drone strikes in the country and ensure access to justice and reparation for victims of violations.''
