"Indonesia strongly condemns Israel's attacks on Iranian diplomatic buildings and facilities in Damascus," said a statement from the ministry, as monitored in Jakarta on the same day.
Ministry of Foreign Affairs called this attack a "violation of international law and the UN Charter", although it did not specify the exact violation. The ministry also said the attack "could erase the prospects for peace" in the Middle East.
"This attack is one of many Israeli actions that have increased the escalation of the conflict and could erase the prospects for peace in the (Middle East) region," the ministry continued.
A British war monitor Syrian Observatory for Human Rights, as quoted by AFP, said the attack killed 11 people. Seven of them were senior officials of Iran's Revolutionary Guard Corps, the organization said. However, Iran's ambassador to Syria, Hossein Akbari, told Iranian television that at least five people were killed.
The Syrian Ministry of Defense said that "the attack destroyed the entire building, killing and injuring everyone inside". The ministry also said work is underway to recover the bodies and rescue the wounded from under the rubble.
Israel said it would not comment on the reported attack. However, Iranian officials reportedly "vowed a stiff response". This is due to fears of further violence between Israel and Iran's allies, triggered by the war in Gaza, Palestine.
