The Syrian Observatory for Human Rights, a British-based Syrian opposition group, said the Israeli attack was aimed at Hezbollah's warehouses in al-Kusa and Jumaria on the outskirts of the capital, Damascus.

They report that the 'Israeli attack' is targeting warehouses of Hezbollah militias in al-Kiswah and Jamraya.

There are also reports of explosions south of Tartus from Saif and the villages of Homs.

The regime-affiliated radio station "Sham FM" reports that a fire broke out at Damascus International Airport and two flights were delayed "due to aggression."
