Saudi Arabia has abandoned its position as mediator in Lebanon, making it less likely that a speedy resolution to the crisis will emerge.
Last week, Hezbollah and other opposition parties withdrew their support from Prime Minister Saad Hariri's coalition government, forcing it to collapse.
Political and sectarian divisions have also resurfaced following the UN draft indictment into the assassination of former prime minister Rafiq al-Hariri, which is widely believed to implicate Hezbollah.
There are fears that this tension may spill onto the streets.
