Iran held a funeral on Friday for seven officers killed in a suspected Israeli airstrike on the Iranian embassy compound in Syria this week, an unprecedented attack for which Tehran has vowed to take revenge.

State television showed demonstrators carrying pictures of those killed and banners with slogans such as "Death to Israel" and "Death to America."

"No act of the enemy against the sacred Islamic republic will go unanswered," Major General Hossein Salami, the IRGC commander-in-chief, told the crowd gathered in Tehran. "Our brave men will punish the Zionist regime."

The funeral coincided with the annual Quds (Jerusalem) Day, during which Iran stages large state-sponsored pro-Palestinian and anti-Israel rallies nationwide.

Among those killed in Monday's airstrike on the Iranian embassy compound in the Syrian capital, Damascus, was one of Iran's top soldiers, Brigadier General Mohammad Reza Zahedi, a senior commander in the Revolutionary Guard (IRGC).

It was the boldest and deadliest in a series of attacks that have killed Iranian officials in Syria since December.

Iran vows to retaliate

Iran vowed harsh retaliation, raising the specter of a wider war and prompting the Israeli armed forces to suspend leave for all combat units on Thursday, a day after they said they were mobilizing more troops for air defense units.

Israeli Prime Minister Benjamin Netanyahu said on Thursday his country would harm "whoever harms us or plans to harm us."

The coffins of two of the killed officers were displayed in the capital, Tehran, to religious mourning chants. Some of those present waved the Palestinian flag. All seven officers were expected to be buried later on Friday.

Iran's Jerusalem Day rallies are held annually on the last Friday of the Muslim fasting month of Ramadan in support of Palestinians, who want East Jerusalem as the capital of a future state in territories won by Israel in a 1967 war.
