Washington: The US will withdraw virtually all family members of US troops and diplomats from its installations in Turkey, US officials have said, citing security concerns as the campaign against the Islamic State continues.

The military decision was announced on Tuesday on the blog for the US European Command, which also instituted travel restrictions in Brussels last week after the terrorist attacks that killed 38 people, including three suicide bombers. At least four Americans died and about a dozen more were wounded, including an Air Force officer who was stationed in Europe and members of his family.

"We understand this is disruptive to our military families, but we must keep them safe and ensure the combat effectiveness of our forces to support our strong Ally Turkey in the fight against terrorism," Air Force General Philip Breedlove, the commander of the European Command, said in a statement.
