A photo released by the Syrian Arab News Agency shows destruction from what is said was bomb attack in the Al-Hama area of Damascus on Sunday, May 5.
Iran has no doubt Syria will deal a "crushing response" to Israel and the Shiite regime stands ready to train its ally's soldiers, officials in Tehran have said.
The remarks, delivered by various Iranian officials and reported in state media, came Sunday after Syria claimed that Israel launched a fresh attack inside its borders.
"As a Muslim and friendly country, we stand by Syria and if there is need for training, we will provide them with necessary training," Brig. Gen. Ahmad-Reza Pourdastan, commander of the Iranian Army's Ground Forces, told reporters Sunday, as cited by CNN.
Around the same time, Iranian foreign ministry spokesman Ramin Mehmanparast said he had no doubt Syria and its allies will "give a crushing response to the aggressions of the Zionists," the state-run IRNA news agency reported.
Israel has not confirmed or denied that it fired rockets that hit a military research center in the Damascus suburbs Sunday.
But Syria says it was the second Israeli airstrike in three days, and Deputy Foreign Minister Faisal al Mekdad told CNN the attack was a declaration of war by Israel.
The airstrikes have riled Syria's allies in the region: Iran and the Lebanese militant group Hezbollah.
