Amnesty said victims they interviewed with no apparent connection to militant groups have either received no compensation or inadequate assistance from the Pakistani government.
The top political official in North Waziristan gave Bibi's family around $100 to cover medical expenses for the children injured in the strike, even though the total cost to the family, including loss of livestock and repairs to their home, was around $9,500, the rights group said. None of the victims in the attack on the labourers received compensation, Amnesty said.
The US drone policy sets a dangerous precedent "that other states may seek to exploit to avoid responsibility for their own unlawful killings,'' said Amnesty.
"The USA and Pakistan both have obligations under international law to investigate these and any other cases where unlawful killings might have occurred, and deliver justice,'' said the report. "But the USA's persistent refusal to acknowledge these strikes, coupled with Pakistan's ambiguous attitude towards the drone program and limited governance in the Tribal Areas, make it almost impossible for victims to secure the redress they need.''
