A short BBC News report:
President Obama's counter-terrorism adviser has given the most detailed explanation so far of America's use of drones to kill members of al-Qaeda....Brennan has gone further than anyone so far in laying out the rationale for a policy that remains controversial.
Slightly off-topic, no 100%, but needs a mention:
Mr Brennan also said that documents found at the compound where Osama Bin Laden was killed in Pakistan last year would go online later this week.
