Ministers of the Hezbollah group and its allies have walked out of a Lebanese Cabinet meeting meant to discuss the country's worsening garbage crisis, reflecting the government's lingering dysfunction despite mass protests.

Prime Minister Tammam Salam had called for the emergency meeting after a weekend of clashes between security forces and demonstrators protesting against corruption and poor public services.

The six ministers withdrew four hours into the meeting on Tuesday. Foreign Minister Gibran Bassil said he was pulling out because of a "theater" being performed with regards to the trash issue.

Lebanon's multi-sectarian power-sharing government has been without a president for more than a year, and parliament has extended its term twice without elections.
