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.

AFP reports that French President Emmanuel Macron accused Damascus of "chemical attacks" against civilians in Syrian rebel enclave of Douma in a call with Trump as the two leaders shared information "confirming" the use of chemical weapons.

AP has added new details:

Syria's state-run news agency says the military's air defenses have confronted a missile attack on air base in central Syria and shot down eight missiles. The report on SANA says the attack on the T4 military airbase in Homs province "is likely to be an American aggression."However, US officials tell AP that the US has not launched airstrikes on Syria.SANA says the attack resulted in a number of casualties.

Pentagon officials say there is no truth to reports that US has launched an attack against Assad bases in Syria.

Regime sources are reporting that Assad's T4 Airbase in Homs is under attack. Earlier @Joyce_Karam reported jets flying east from the Mediterranean across Jounieh, Lebanon. Identity of the attackers not yet known. #Syria

Earlier there were reports of aircraft and missiles over Lebanon:

Been watching these reports of aircraft over Lebanon. I’ve watched/participated strikes/overflight since 1983. It could be Israel aircraft or US cruise missiles but audio is def at low altitude. Jounieh Axis is best entryway for missiles to Central Syria. https://t.co/UrEFaytMdd

Reports of airstrikes against T4 airbase in central Syria. Base was one of Russia's primary operations centres during anti-ISIS campaign. Likely to still host some Russian equipment, possibly personnel.

Reports of airstrikes on the Syrian regime's T4 Airbase in Homs, which is operated by Iran & the IRGC (and was targeted by Israel in February after an Iranian drone entered Israeli airspace). This follows earlier reports of jets flying east from the Mediterranean across Lebanon.
