Britain has "crossed a line" by using RAF drone strikes to target Islamic State militants in Syria and is apparently "conducting summary executions from the air", a worldwide human rights charity has warned.
Amnesty International UK Director Kate Allen said:
It’s extremely alarming that the UK has apparently been conducting summary executions from the air.
In following the United States down a lawless road of remote-controlled summary killings from the sky, the RAF has crossed a line.
If we allow this to become the norm, we could have countries all over the world conducting aerial execution of perceived enemies on the basis of secret, unchallengeable evidence.
Defence Secretary Michael Fallon has suggested there were more names on the list who were legitimate targets for air strikes.

Two British Islamic State fighters were killed by a RAF drone strike in Syria, while a third died during an American attack.
