Further drone strikes against Islamic State militants plotting to attack the UK could be launched within weeks, the Defence Secretary has said.
Michael Fallon said the Government would "not hesitate" to repeat the action that led to Britons being killed by an RAF drone in the Islamic State stronghold of Raqqah last month.
Mr Fallon defended the move and said the Government would use military strikes again if there was no other way to stop the terror cells.
Speaking on BBC Radio 4's Today Programme, he said:
There are other terrorists involved in other plots that may come to fruition over the next few weeks and months and we wouldn't hesitate to take similar action again.
Defence Secretary Michael Fallon has suggested there were more names on the list who were legitimate targets for air strikes.
