Rival Lebanese lawmakers nearly came to blows on live TV on Monday, shoving and shouting at each other in a vivid illustration of political conflict that is paralyzing decision-making and fueling public discontent.

After arguing for several minutes at a parliamentary committee on public works and energy, one MP threw a water bottle, before scuffling with another. The fight was quickly broken up and the meeting abandoned.

Political tensions in Lebanon have been exacerbated by wider tensions in the Middle East, including the Syrian war. A national unity government bringing together rival parties has struggled to pass decisions and the country has been without a president for more than a year.

The crisis came to a head this summer with the government’s failure to agree a solution to a refuse collection and disposal dispute that left garbage festering on Beirut’s streets.

Monday’s altercation began when MP Ziad Aswad, a member of Christian politician Michel Aoun’s Free Patriotic Movement, objected to corruption allegations raised against the minister of energy — who belongs to his political bloc — by a member of a rival alliance led by Sunni politician Saad Al-Hariri.
