The toll from Wednesday's double suicide car bombing at an Iranian cultural centre in Beirut has risen to 10, a health ministry source said.
"The death toll in the blasts has risen to 10 after the remains of an additional four people found at the site of the explosion were identified through DNA testing," the source told AFP Thursday.
On Wednesday, the health ministry had put the death toll at six, with 129 people injured in the attack in the Bir Hassan neighbourhood.
A judicial source said work was still under way to identify the two suicide bombers who carried out the attack, which was claimed by the Abdullah Azzam Brigades, a jihadist group inspired by Al-Qaeda.

The cultural centre is located in the same neighbourhood as the Iranian embassy, which was hit by a double bombing in November that killed 25 people and was also claimed by the Azzam Brigades.
The group said Wednesday's attack was to punish Lebanon's powerful Iran-backed Shiite group Hezbollah and Tehran for their role in the conflict in neighbouring Syria.
Both Hezbollah and Iran back Syria's President Bashar al-Assad, who is battling a Sunni-led uprising.
Extremist groups have claimed responsibility for a series of attacks in recent months against areas considered strongholds of Hezbollah that have killed dozens of civilians.
