Israeli planes had apparently "dropped ammunition" over desert areas of Syria, before being forced to leave, according to the official Syrian news agency, SANA.

Israel radio quoted an unnamed Israeli army source as saying no air strike had been carried out. 

The Syrian news agency says the action took place "without causing human or material loss".

Syria and Israel have remained technically at war since the seizure of the Golan Heights in 1967.

Tensions between Israeli and Syria have been rising in recent months. Both countries' leaders have said they do not want a war.

Syria says it last fired at Israeli warplanes in June 2006, when Israeli aircraft flew over the summer residence of the Syrian president, while he was inside.
