Street protests have broken out overnight over severe water shortages in Iran's oil-rich southwest, according to Iranian news outlets and videos posted on social media, as the country faces its worst drought in 50 years.
Videos showed protesters setting fire to tyres to block a road and security forces were seen trying to disperse the crowds as some shots were heard. Reuters could not independently verify the videos' authenticity.
"State television should report what we are saying and show the image of the buffaloes that perished from lack of water," an elderly protester said on a video carried by the regional Asrejonoob news website.
In May, Iranian Energy Minister Reza Ardakanian warned of water shortages in the summer, saying this year was "one of the driest in 50 years".
The water shortages have led to power blackouts and there were protest marches in several cities last week. During some protests, people vented their anger with Supreme Leader Ayatollah Ali Khamenei, chanting "Death to the dictator" and "Death to Khamenei".
In recent weeks, thousands of workers in Iran's key energy sector have held protests, seeking better wages and working conditions in southern gas fields and some refineries in big cities.
Iran's economy has tanked due to the impact of US sanctions and the COVID-19 pandemic. Nowhere in the Middle East has been hit harder by the virus than Iran.
Protests by workers and pensioners have been almost unrelenting for months, with discontent growing over an economy that is suffering inflation of more than 50 per cent, high unemployment, with some workers complaining that their wages are not being paid.
