Missiles were allegedly fired at the Syrian regime's Shayrat airbase near Homs and an airbase in the capital Damascus.
Syrian air defences intercepted missiles over Homs which targeted Shayrat air base late on Monday night, Syrian state television reported. No country has yet claimed the attack after midnight but United States officials recently said that Washington wasn't planning another strike after the missile strike on Saturday.
The heavily armed and Tehran-backed Shiite movement has been a vital military ally of President Bashar al-Assad in the seven-year-old Syrian war.
