Protesters and security forces clash in Lebanons anti-government rally.

Protesters clashed with Lebanese security forces at anti-government demonstrations in Beirut on Thursday.

Officers deployed tear gas on dozens of people near parliament.

Tuesday’s devastating blast had angered demonstrators.

Officials say the blast was caused by 2,750 tonnes of ammonium nitrate stored unsafely since 2013.

Many in Lebanon say government negligence led to the explosion, which killed at least 137 people and injured about 5,000 others.

The explosion destroyed entire districts in the capital, with homes and businesses reduced to rubble.

Dozens of people are still unaccounted for.
