A double suicide bombing outside the Iranian embassy in the Lebanese capital Beirut has killed at least 22 people.
A Lebanese Sunni group linked to al Qaeda, Abdullah Azzam Brigades, said it was behind the attacks.
Iranian cultural attache Sheikh Ibrahim Ansari is among the dead , according to the Fars news agency.
Lebanese officials said the first suicide attacker was on a motorcycle, while the second was in a four-wheel drive vehicle. The explosions on Tuesday injured more than 140 people.
The United Nations Security Council condemned the bombings and the US described them as "senseless and despicable".
The BBC reports the number of people killed in Tuesday's attack makes it one of the worst in Shi'ite southern Beirut since the war across the border in Syria began, and is the first attack on an Iranian target.
