Saudi Arabian police clashed with foreign workers in a poor district of Riyadh on Saturday, nearly a week into a visa crackdown in which thousands have been detained and one man killed by police.
Security forces in riot gear fired into the air and used truncheons to disperse large crowds as scores of men ran through the streets, some throwing stones and other missiles at cars and police, according to Reuters witnesses.
It was not clear if many people had been injured in the disturbances in the Manfuhah neighborhood of southern Riyadh, but there were ambulances among the emergency vehicles at one location. Most of the foreign workers involved in the clashes appeared to be Africans.
Authorities this year said they would no longer turn a blind eye to foreign workers breaking visa rules by working for companies that had not sponsored their entry into the world's top oil exporter.
The intention is to end a black market for cheap imported workers, cut the foreign labor force, reduce the flow of remittances to other countries and make more private sector jobs available for Saudi citizens.
