The State Department and Pentagon ordered the families of U.S. diplomats and military personnel Tuesday to leave posts in southern Turkey due to "increased threats from terrorist groups" in the country.

The two agencies said dependents of American staffers at the U.S. consulate in Adana, the Incirlik air base and two other locations must leave. The so-called "ordered departure" notice means the relocation costs will be covered by the government.

In a statement, the military's European Command said the step "allows for the deliberate, safe return of family members from these areas due to continued security concerns in the region."

The orders cover the Adana consulate, U.S. military dependents in Incirlik, Ismir and Mugla as well as family of U.S. government civilians at Ismir and Mugla. The State Department also restricted official travel to that which it considers "mission critical."
