TUNIS - A US-based rights group accused pro-Gaddafi forces of using cluster munitions in the Libyan rebel-held city of Misrata, endangering civilians.
A Libyan government spokesman rejected the allegation.
Cluster munitions -- fired from artillery or rockets -- can scatter bomblets over a wide area. They often fail to detonate immediately and may explode years after a conflict, killing or maiming people, according to humanitarian groups.
Human Rights Watch said in a statement that government forces had fired cluster munitions into residential areas in the western city of Misrata, "posing a grave risk to civilians".
