Islamic militant groups have carried out nearly 50 attacks on U.S. bases since Oct. 17, when Hamas claimed Israel attacked a Gaza hospital.

The U.S. carried out an airstrike in Syria as American forces come under increasing attack in the Middle East.

In less than two weeks, U.S. forces in the Middle East have come under attack 23 times, the Pentagon says.

"We will take all necessary actions to ensure that our forces are protected and that our interests overseas are protected."

American fighter jets struck weapons depots in Syria that had supported the attacks on U.S. troops in the Middle East.

More details have emerged revealing that the barrage intercepted by the USS Carney was much "more sustained" than initially reported.

A day after American troops were fired on in Iraq, new reports say they have been attacked in Syria as well.

In the 10 days since Israel was attacked, it has struck targets not only in Gaza, but also in Syria and southern Lebanon.

Hezbollah confirmed it had fired anti-tank missiles and claimed “a large number of confirmed casualties” had been inflicted.

In recent weeks, U.S. officials said, Russian fighter jets have repeatedly harassed U.S. MQ-9 drones in western Syria.
