A car bomb struck a complex used by Hezbollah in a Beirut suburb, killing at least 20 people and injuring over 200 more. Shortly after the blast, a video was released by a previously unknown Syrian Sunni group, the Aisha Umm-al Mouemeneen, claiming the attack and warning Hezbollah. The head of Hezbollah claimed that his group was responsible for a bomb attack on Israeli soldiers at the Lebanese border last week and threatened further attacks for alleged Israeli incursions.
