South Africans are getting sick of the country being flooded with immigrants - while they themselves suffer massive unemployment - and organised an anti-immigration march on Friday in Pretoria. A group of Somalian migrants brought weapons to take on the marchers and clashes ensued with the police firing rubber bullets and stun grenades at both sides.

Legal and illegal African immigrants to South Africa, which has the continent’s most advanced economy, have been the focus of criticism and resentment and sometimes of violent attacks in recent years. South Africans accuse migrants of stealing jobs or exploiting locals by running small businesses in poor, black townships.

Others blame foreigners for the country’s high crime rates. The accusations, which are not backed up by official statistics, resonate in a country with a jobless rate of 27-percent and yawning income inequalities.

The latest anti-immigrant sentiments were set off in a neighborhood south of Johannesburg called Rosettenville, where residents burned down a dozen houses that they said were being used by Nigerians as drug dens and brothels.

Protesters handed the foreign ministry a petition that calls on the government to teach foreigners how to speak properly, according to the Associated Press news agency.

"They are arrogant and they don't know how to talk to people," the petition said, singling out Nigerians.

At least there were no wacists involved - as only white people can be wacists
