Lebanon’s political discord has intensified with the collapse of its national unity government. On Wednesday, ministers with the Hezbollah-led political bloc pulled out of the Lebanese cabinet, toppling Prime Minister Saad al-Hariri’s ruling coalition. The resignations came after Hariri rejected Hezbollah’s calls for the convening of a meeting to address concerns over a U.N. probe into the 2005 assassination of Hariri’s father, former Lebanese Prime Minister Rafik al-Hariri. There have been rumors the U.N. tribunal is preparing to indict Hezbollah members for Hariri’s death. Hezbollah has denied involvement in the assassination and denounced the U.N. probe as a tool of the United States.
