The Guardian reports:

Campaigners against US drone strikes in Pakistan are calling for the CIA’s former legal chief to be arrested and charged with murder for approving attacks that killed hundreds of people.

Amid growing concern around the world over the use of drones, lawyers and relatives of some of those killed are seeking an international arrest warrant for John Rizzo, until recently acting general counsel for the American intelligence agency.

Opponents of drones say the unmanned aircraft are responsible for the deaths of up to 2,500 Pakistanis in 260 attacks since 2004. US officials say the vast majority of those killed are “militants”. Earlier this week 48 people were killed in two strikes on tribal regions of Pakistan. The American definition of “militant” has been disputed by relatives and campaigners.

The attempt to seek an international arrest warrant for Rizzo is being led by the British human rights lawyer Clive Stafford Smith of the campaign group Reprieve, and lawyers in Pakistan. The lawyers are also building cases against other individuals, including drone operators interviewed or photographed during organised press facilities.
