Two massive blasts outside of the Iranian embassy in Beirut, Lebanon on Tuesday have left at least 20 people dead and 140 injured.

Among the dead was the Iranian embassy's cultural attache, according to Iran's Fars News Agency. Fars reported Tuesday that the head of the embassy's security and five guards were also killed.

According to the BBC, the terrorist group said that Tuesday's attack was a "double martyrdom operation carried out by two heroes from the heroic Sunnis of Lebanon."

The attacks appear to be in response to the Iranian government's support of Hezbollah and the Syrian government, who is fighting against rebel forces in a nearly three-year-old civil war.
