On Friday, a bomb exploded in Beirut’s eastern Ashrafiya district, and killed eight people and injured more than 78 others.
The explosion occurred near the headquarters of the Phalange, a Maronite Christian party. Several buildings were damaged and many cars were set on fire as a result of the blast.
The intelligence chief of Lebanon’s Internal Security Forces, General Wissam al-Hassan, was among those killed in the explosion. He had recently dismantled an Israeli spy cell in Lebanon.
Lebanese Prime Minister Najib Mikati said the government was trying to identify the perpetrators and that they would be punished.
