Syria, Israeli air strikes hit an arms supply hub operated by the Lebanese Hezbollah group near Damascus airport where regular supplies of weapons from Tehran are sent by commercial and military cargo planes.

The source said the arms depot gets a major part of the weapons supplied to an array of Iranian backed militias, led by Hezbollah, which have thousands of fighters engaged in some of the toughest fronts against Syrian rebels.

Witnesses said a total of five strikes occurred near the Damascus airport road early today. The airport lies about 25 kilometers south-east of Syria’s capital. The Syrian Observatory for Human Rights says the blast was huge and could be heard in Damascus. The blast was reportedly followed by a large fire. There is no word on casualties.
