GOMA: M23 fighters on Friday advanced further on several fronts in DR Congo`s volatile east as international pressure mounted on Rwanda to stop backing the armed group and halt the fighting.

The M23 which is supported by some 4,000 Rwandan soldiers according to UN experts took control of the South Kivu provincial capital Bukavu on Sunday, just weeks after capturing Goma, the capital of North Kivu and main city in the Democratic Republic of Congo`s mineral-rich east.

The gains gave M23 control of Lake Kivu following its blitzkreig in the east. According to the United Nations, the latest fighting has led to an exodus of over 50,000 Congolese to Burundi, Uganda and other countries.

The European Union on Friday summoned Rwanda`s ambassador to demand Kigali pull out troops from the country and stop backing the armed group. The EU`s move comes a day after Germany summoned the Rwandan ambassador and the United States imposed sanctions on Rwanda`s minister for regional integration James Kabarebe.

Since the fall of Bukavu, the Congolese armed forces have been retreating without of fering much resistance. `Almost no Congolese soldiers are fighting`, an observer said on Friday, adding that the `only ones still fighting are the Wazalendo` or pro-Kinshasa militia.

The North Kivu city ofMasisi and its surroundings `are the scene of almost daily clashes` between the M23 and Wazalendo, medical charity MSF said. The M23 is now moving towards the town of Uvira near the Burundi border on the northwestern tip of Lake Tanganyika the main exit route for fleeing Congolese soldiers.

Around 42,000 people have fled the conflict and crossed into Burundi in the past two weeks, the United Nations said on Friday. A source in Uvira`s municipality said the military commander had taken `measures to secure the population and their property`, adding that `undisciplined elements had been arrested`.

Uvira residents had tsaid that chaos reigned in Uvira. On Wednesday, hundreds of soldiers and their families crossed the town on foot to reach the port. At least 423 inmates from Uvira prison have escaped and the bishop of Uvira was robbed and held up by armed men at his workplace.

A few days earlier, South Kivu governor Jean Jacques Purusi was the target ofan attack by proKinshasa militia at his hotel in Uvira. A number of soldiers and police protecting the governor were killed, his secretariat said.

On the northern front, which has been relatively stable since December, M23 fighters are now just 15 kilometres (nine miles) from the centre of Lubero, a strategic town. Some Congolese soldiers have fled Lubero.-AFP
