Assad office says US strike 'foolish, irresponsible'

A US missile strike on an airbase in central Syria early on Friday was "foolish and irresponsible," President Bashar al-Assad's office said.

"What America did is nothing but foolish and irresponsible behaviour, which only reveals its short-sightedness and political and military blindness to reality."

"This aggression has increased Syria's resolve to hit those terrorist agents, to continue to crush them, and to raise the pace of action to that end wherever they area," a statement from the presidency said.

He denied that his government had carried out a chemical attack this week and said that Washington was "naively pulled behind a false propaganda campaign".
