At least five explosions have been heard in the Syrian capital.
The blasts in the early morning hours of Sunday shook buildings in Damascus.
The Lebanese Al-Mayadeen TV station, which is close to the Syrian government, reports that the blasts came from direction of the Mezzeh military airport, southwest of the capital. Locals report on social media seeing fires and hearing explosions from that direction.
Syria's government has accused Israel of carrying out a number of strikes on the Mezzeh airport in the past. Israel rarely admits to strikes inside Syria but says it will use military action to prevent weapons transfers to its enemies inside Syria.
