Authorities in Beirut have launched an investigation into the double suicide bombing outside the Iranian embassy in the Lebanese capital.
More than twenty people died in the blasts and more that 100 were injured.
The Lebanese based Sunni Muslim militant group Abdullah Azzam Brigades have claimed responsibility for the attack.
There is a mood of defiance on the streets of Beirut, a city all too familiar with acts of violence: “My response is to the point and uncompromising, because Lebanon has been attacked. Lebanon is a country that resists and our enemies do not want it to resist, the Gulf countries, the United States and Israel our main enemy,” said one man.
Another issued a warning: “No matter what they do and the number of people they kill I have a quote for Imam Khomeini and it goes like this, “Kill us and our people will become more aware and more conscious.”
The Abdullah Azzam Brigades, have threatened further attacks unless Iran withdraws its forces from Syria, where they have backed President Bashar al-Assad’s 30 month war against rebel fighters.
