The Lebanese Movement of "Amal" on Sunday denied that its members have taken part in riot acts in downtown Beirut.

In a statement earlier in the day, the movement's information office said that media reports about the movement's participation in the violent acts in downtown are completely false and groundless.

The reports are meant to instigate violence, the movement added.

Saturday and Sunday saw the biggest demonstration by far since garbage began piling up on the streets after the capital's main landfill was closed a month ago.

The government has been unable to find an alternative system for waste management amid government paralysis and bickering among politicians.

The health minister has warned of a catastrophe as some have started dumping trash in valleys, rivers and near the sea.

The clashes escalated on Saturday and Sunday after protesters accused the government of corruption and political dysfunction amid a trash crisis.

The army and police have taken action against the protesters after they have been accused of committing violent acts in the capital's downtown.
