UN warns the "seeds of genocide" are being sown in Central African Republic There has been relative calm since Mr Djotodia resigned last week under intense international pressure, but sporadic violence has persisted in Bangui. On Thursday, a spokesman for a 15,000-strong group of anti-balaka criticized the interim government and threatened a return to violence if it was not overhauled. "If there is no solution to this, we always have our machetes which we have not yet handed in," the spokesman, Sebastien Wenezoui, told Reuters at a base in the northern Bangui suburb of Boeing, flanked by around 20 militiamen armed with knives, machetes and Kalashnikovs. His group wants the country's transitional assembly (CNT) to be reworked to boost the presence of the anti-balaka and reduce the number of Seleka representatives. It plans a march in Bangui on Friday to try to stop the appointment of a new interim president, he added. The UN's new warning echoes one given by UNICEF's roving ambassador, the actress Mia Farrow, in an interview with the Sunday Telegraph in November. Speaking just after returning from a visit to the CAR, she said: "The violence and instability is increasing, and the seeds are present for a genocide." The CNT is due to vote on the new head on January 20, its vice president Lea Koyassoum Doumta said on Thursday. Central African Republic is designated by the United Nations as one of the top three global humanitarian emergencies, along with Syria and the Philippines. But a U.N. appeal has received only 6 percent of a $247 million target. Returning from a five-day trip to the country, a U.N. official said the crisis was foreseeable and stemmed from many years of international neglect of the chaotic country. Mr Ging said the country amounted to little more than a territory on a map, without state infrastructure and functioning security forces. He said French and African Union (AU) peacekeepers were having a positive effect but were stretched to their limits. "Central African Republic has to move up the priority list," he said. However desperate and alarming the situation might be right now, it can be turned around very quickly. France hurriedly sent some 1,600 troops to its former colony in December. The deployment of Rwandan troops, the first of whom arrived aboard a US military aircraft on Thursday, will increase the AU contingent to more than 5,000 peacekeepers this month. Many say the bloodshed has little to do with religion, in a nation where Muslims and Christians have long lived in peace. Instead, they blame a political battle for control over natural resources in one of Africa's weakest states, split along ethnic lines and worsened by foreign meddling. Around 20 more people were killed on Thursday when anti-balaka fighters attacked a convoy of Muslims, many of them women and children, headed for the town of Bouar, 280 miles to the west of Bangui, witnesses said. The families were fleeing militia attacks in the nearby town of Bohong. There were about 20 lifeless bodies strewn here and there on the road. Some were killed by bullets, others with knives," Achille Yakende, a salesman travelling to Bouar by motorbike, told Reuters. In Bangui, hundreds of angry residents surrounded a convoy of Chadian Muslims fleeing the country. They shouted "go home" and "assassins." Some in the crowd tried to loot and set fire to one vehicle but were prevented by AU peacekeepers, who fired warning shots to disperse them. At least eight people were killed late on Wednesday in violence in the north of the capital, witnesses said. The commander of French forces, General Francisco Soriano, told a video conference in Paris the security situation was improving, but still "extremely complicated and very volatile."
