Reports are emerging on Twitter that a Syrian airbase or military airport in Homs is under attack, possibly by US or Israeli aircraft.
But so far there is no confirmation of who is attacking.
The Guardian's world editor Julian Borger tweeted: Pentagon official on Syria: "We are aware of the
reports. We have nothing to confirm."
This morning US President Donald Trump said there would be a "big price to pay" after medical aid groups reported dozens of people were killed by poison gas in a besieged rebel-held town in Syria.
At least 40 people were killed, including families found in their homes and shelters, opposition activists and local rescuers say, Reuters reports.
