More than 100 people have been killed since Friday in Sudan\'s strife-torn Darfur region in clashes between two tribes over land, Reuters quoted tribal sources as saying on Sunday. Tribal sources said thousands of members of the Rezeigat tribe attacked their Maaliya rivals in a bid to seize territory. \'Clashes took place on Saturday and Friday which resulted in the deaths of 41 from our side and 90 wounded,\' Aydam Abu Bakr, a leader of the Rezeigat tribe, said by telephone. He said 70 people on the Maaliya side were also killed. More than 500 people were killed in clashes between two tribes fighting for control of a gold mine in North Darfur in January and February.
