At least seven people were killed in clashes between rival political supporters in Togo's capital this weekend, a rights group and party officials said, as fear gripped an edgy city ahead of presidential polls next Sunday. A rights group close to the ruling party said six of that group's supporters were killed and around 100 injured in street fighting in a northern suburb of Lome on Saturday. An opposition leader said one of their members was killed and 55 hurt. Both sides blame each other for provoking the first serious clashes between the rival groups since elections were called to end a political crisis in the West African nation.
