Police in Ivory Coast are trying to disperse demonstrating supporters of Alassane Ouattara, the UN-backed winner of disputed presidential elections. They want to march towards the state television in central Abidjan with the intention of seizing it. The army, loyal to incumbent President Laurent Gbagbo, is surrounding the station - and accuses the marchers of deliberately provoking confrontation. The UN has refused a request from Mr Ouattara's camp to secure the march. The UN chief Ban Ki-moon urged both sides to refrain from doing anything that could provoke violence. "The secretary general is reminding those who incite or perpetrate violence, and those who use the media for that purpose, that they'll be held accountable for their actions," his spokesman Martin Nesirky told the BBC's Network Africa. He also reiterated Mr Ban's call for Mr Gbagbo to stand down. "The secretary general has called repeatedly on Mr Gbagbo to respect the will of the Ivorian people," Mr Nesirky said. Heavy arms The BBC's John James in Abidjan says shots have been fired in the air by the security forces and teargas used to disperse demonstrators in outlying districts of the city. He says there is a high security around the television station, with army tanks blocking the main boulevards. Mr Ouattara and his Prime Minister Guillaume Soro have been confined to the waterfront Hotel Golf since the impasse over the election results began two weeks ago. The hotel is guarded by the UN, which has about 10,000 peacekeepers in the country that was divided by civil war in 2002. Fighters from the New Forces (FN), Mr Soro's former rebel group that still controls the north of the country, are also guarding the hotel. The electoral commission declared that Mr Ouattara won the run-off by 54.1% to 45.9%, but Mr Gbagbo immediately refused to concede power. A Constitutional Council then annulled some results from the north and declared Mr Gbagbo the winner. Our reporter says Mr Ouattara's supporters are keen to gain control of the state television which has been broadcasting reports in praise of Mr Gbagbo. An official march led by Mr Soro and his ministers is expected to head towards the television station. Most shops and businesses were shut and the city streets around the centre are deserted, our correspondent says. Source: BBC
