Fresh fighting erupted Sunday between Somalia’s transitional government forces and Islamist rebels, continuing a wave of violence that a top United Nations official called a "grave violation of human rights" that could possibly amount to war crimes. The 37-year-old Canadian, who was born in Italy and made his name as a fighter based in New Jersey, was staying in the north-eastern seaside resort of Porto de Galihnas. Police are investigating, with several media reports suggesting foul play.
