Congo city of Lubumbashi attacked by 240 fighters

Residents say hundreds of fighters from a Congolese militia have attacked the southeast mining center of Lubumbashi.

The governor of Katanga province, Moise Katumbi, appealed for calm Saturday after a day of panic sparked by the arrival of the Mai Mai fighters.

U.N.-run Radio Okapi reported that 240 fighters - armed with bows and arrows and machetes - had surrendered to the U.N. peacekeeping force. Children were reportedly among the militia when it attacked the city.

It was not immediately clear how many people were killed or wounded in the violence.

The Mai Mai militiamen are seeking to secede from Katanga province. Eastern Congo is home to a myriad of rebel groups who terrorize civilians, though most attacks are further north in the North and South Kivu provinces.
