US confirms four American citizens killed by drones

[mhm]

The US attorney general has acknowledged four US citizens have been killed in drone strikes since 2011.

In a letter to the Senate judiciary committee, Eric Holder defended the targeted killing of Anwar al-Awlaki.

But he said Awlaki's 16-year-old son as well as two other individuals were "not specifically targeted by the US".

The disclosure comes as President Barack Obama prepares to make a speech on counter-terrorism and the drone programme on Thursday.
