Swiss police fire water cannon, tear gas at Cameroon protesters

GENEVA: Swiss police fired water cannon, tear gas and stun grenades at Cameroonian protesters outside UN headquarters in Geneva Saturday as the crowd surged towards a luxury hotel hosting Cameroon's president.

Parts of the "city of peace" resembled a war zone, with police wearing gas masks and black riot gear chasing demonstrators through Geneva´s international neighbourhood, shooting tear gas canisters into the gardens of high-end residences where some tried to hide.

About 250 demonstrators, many dressed in military-style garb and draped in Cameroonian flags, initially gathered on a square outside the UN, with laughter and loud music creating a festive atmosphere.

But things turned violent when the crowd suddenly began running towards Biya´s hotel, about 500 metres (1,600 feet) away, chanting "Biya Assassin!" and "Switzerland Complicit" as they attempted to break through tight lines of police backed up by armoured vehicles.

Police used pepper spray and turned a water cannon, mounted on top of a tank, on the demonstrators.

An AFP reporter witnessed police beating and kicking a protester on the ground.

Biya, 86, "has run his dictatorship for nearly half a century," said rally co-organiser Robert Wanto, a Cameroonian national who has lived in exile for three decades.

"We are here to demand that Cameroon be allowed to enter the modern democratic era," he told AFP.

Cameroonian nationals exiled in a range of countries, including France, Italy, Spain, Britain and Denmark were said to have come to take part in the demonstration.

Police had to intervene to rescue a Biya supporter, who walked into the crowd wearing a dress with pictures of the president and shouting insults at the protestors, prompting a large group to attack her.

Geneva police told AFP the demonstration was authorised, but limited to the square outside the UN.

They were not granted permission to march to the five-star Intercontinental Hotel where Biya, who has ruled Cameroon since 1982, is believed to have been staying since Sunday.

But Wanto told AFP before the protest the demonstrators had given Biya an "ultimatum" to leave, and would march on the hotel if he remained there.

He pointed out that Biya had made it a habit to stay at the pricy Intercontinental during long visits to Switzerland, where he reportedly comes for medical treatment.
