Lebanon has arrested 11 people over last week’s Beirut bombings, officials said on Sunday.
Twin suicide bombings rocked the area of Bourj al-Barajneh south of Beirut Thursday, killing at least 43 people and injuring over 250 others.
The Islamic State jihadist group claimed responsibility for the Thursday’s attacks.
Investigators also identified the network behind the operation.
Interior Minister said the seven Syrians were detained in a Palestinian refugee camp that had been used to prepare the explosive belts.
Security forces arrested the Lebanese would-be suicide attacker in the northern port city of Tripoli after he had failed to detonate his suicide belt.
The internal security services later announced the arrest of two other suspects, a Lebanese and a Syrian.
