Syrian official says Damascus will respond to Israeli attacks against targets on its territory.

Damascus will respond to Israeli attacks against targets on its territory, but will "choose the moment" and may not do so immediately, a Syrian political official said on Monday.

"Syria will respond to the Israeli aggression and will choose the moment to do so," the official close to the regime, who was speaking from Damascus, told AFP in Beirut.

Syria responded earlier to the air strikes on military targets with a warning that the attack "opens the door to all possibilities."

"We will not accept to be humiliated," Syrian information minister Omran al-Zoubi said at an afternoon press conference, according to ABC News.

"We are all in a state of anger. We are abused by this attack," he added.
