Irish Taoiseach (Prime Minister) Leo Varadkar has said Ireland will take back extremists who have traveled abroad to fight with Islamic terrorist groups.

The announcement comes just days after the UK moved to revoke the citizenship of “ISIL bride” Shamima Begum, who left London to join ISIL (also known as ISIS) in Syria but now wants to return home.

While indicating each case would have to be considered on its own merits, Varadkar said: “I’d be very loathe to revoke anyone's citizenship, provided they are a citizen by right or acquired their citizenship lawfully or appropriately."

"I think its bad practice to revoke someone's citizenship and render them stateless and leave them to be someone else's problem," he said.

He said there may be "as few as one" jihadi who has left Ireland and would be in a position to return.

Senior Gardaí (Irish Police) security and intelligence officers reckon that many of the 30 suspects, who left Ireland to join foreign fighters in Syria and Iraq, are now dead.

Others are missing and some may have headed to other "theatres of war" such as in the Philippines, the Horn of Africa and North Africa.
