Jennifer Glasse reports from Kenya on the string of violent attacks in and around the Indian Ocean port of Mombasa since last week. Some thirty people have died in the incidents, which began with an attack on a police post last Wednesday. Mombasa is Kenya's second-largest city and the destination for thousands of beach-going foreign tourists. No tourist has been harmed so far. Some local residents say the unrest is related to an ongoing ethnic conflict in the region.
