KINSHASA: Heavy fighting in the city of Kananga in central Democratic Republic of Congo has claimed many lives, concurring sources said.

The violence erupted on Thursday and continued into Friday, with attacks on the city’s airport by supporters of a tribal chief who was killed in August by the military, they said.

“There was a bust-up in Kananga but calm returned in the late afternoon,” DR Congo government spokesman Lambert Mende told AFP.

At least 10 people were killed, according to an incomplete AFP toll compiled from various sources.

The vast central African country, a former Belgian colony, is chronically unstable and is the theatre of conflict between many rival groups.

Central government is also in the grip of a political crisis.

Rioting and protests against President Joseph Kabila on Monday and Tuesday claimed at least 50 lives, according to the UN.
