Arizona Tribune - Fighting erupts in DR Congo a day after peace deal signed

Thursday's agreement was meant to stabilise the resource-rich east but it has had little visible effect on the ground so far, in an area plagued by conflict for 30 years.

Fighters from the anti-government armed group M23 battled on Friday in South Kivu province with the Congolese army, backed by thousands of Burundian soldiers deployed alongside it.

Both sides are fighting for control of the border town of Kamanyola -- where the Democratic Republic of Congo, Rwanda and Burundi meet. M23 is currently in control there.

Detonations that shook buildings echoed throughout the morning near Kamanyola, an AFP journalist reported in Bugarama, a border post on the Rwandan side some two kilometres (1.3 miles) away.

On Friday, the M23 accused the Burundian army of firing "without interruption" into the DRC.

A Burundian military source told AFP they were reinforcing their positions to ensure they were not overrun by M23 fighters and their Rwandan backers.

"The fighting is intensifying," the source added, speaking on condition of anonymity. "There is a real risk the situation escalates.

"We are bringing reinforcements to the front because this is a red line for Burundi."

The source said his country could not accept it if "the terrorists of M23 and their Rwandan backers reach Uvira", a city in DRC less than 30 kilometres from the Burundian capital Bujumbura.

-'Schools, hospitals' shelled -

Lines of civilians fleeing the fighting crossed the border in the early hours watched by Rwandan police.

"The bombs were exploding above the houses," said one witness, Immaculee Antoinette, from Ruhumba, near Kamanyola.

"We were asked to remain locked inside our houses, but that seemed impossible."

Hassan Shabani, an administrative official in Kamanyola, said "schools, hospitals and civilian homes" were all shelled.

On the Rwandan side, some residents were "scouring the hills from where the shots are coming, in small groups", said local Farizi Bizimana.

"The children and women are very scared and take refuge in houses when the gunfire becomes intense," she added.

In January, M23 backed by Kigali and its army went on the offensive, capturing the major regional cities of Goma in North Kivu province and Bukavu in South Kivu.

On Thursday in Washington, Congolese President Felix Tshisekedi and Rwandan President Paul Kagame signed an agreement that their host, US President Donald Trump, dubbed a "miracle".
