Kigali - Rwandan police say a grenade attack in a northern town has wounded at least six people, two of them critically.
Regional police spokesman Emmanuel Hitayezu said on Tuesday that two men on a motorcycle hurled a grenade at people gathering near a taxi stop before speeding away.
He said the attack happened on Monday night near the Rwandan Police College in the district of Musanze.
Rwanda has seen a series of grenade blasts in recent times that authorities often blame on dissident groups.
Some of the grenade attacks have targeted the capital, Kigali.
Last September, two people were killed and dozens wounded in two simultaneous grenade blasts there.
