One of the most respected sources of investigative reporting on drones is The Bureau of Investigative Journalism, a non-profit organization based in London. As part of its research, TBIJ tracks drone strikes and other US military and paramilitary actions in Yemen, Somalia and Pakistan. Yesterday, TBIJ released its summary for June [6]. The major conclusions:

• As relations between Washington and Islamabad continue to falter, Bureau data shows fewer civilians are being killed in CIA drone strikes in Pakistan [7] than at any time in the Obama presidency.

• US military action in Yemen [8] is at its bloodiest ever, with the strike rate and reported casualties the highest yet recorded.

• The true extent of US action in Somalia [9] remain unclear, despite many claims of attacks.

The report also provides a comparison of the first 6 months of this year with 2011.
