An Islamist attack on a hotel in the Somali capital ended on Sunday after 25 people had been killed in a near 12-hour siege, police said, underlining the insurgents' ability to carry out deadly attacks in the heart of the city."The death toll rises to 25 people including police, hotel guards and residents. The death toll may rise. We suspect some other militants disguised themselves and escaped with the residents who were rescued," police officer Major Mohamed Hussein told Reuters."Three militants were captured alive and two others blew up themselves after they were shot," he added.
