An al-Qaeda-linked Somali militant group suspected in twin bombings in Uganda's capital that hit crowds watching the World Cup final endorsed the attacks Monday but stopped short of claiming responsibility, while the death toll rose to 74. The blasts came two days after a commander with the Somali group, al-Shabab, called for militants to attack sites in Uganda and Burundi, two nations that contribute troops to the African Union peacekeeping force in Somalia. Ugandan government spokesman Fred Opolot said Monday that there were indications that two suicide bombers may have taken part in the attacks late Sunday that left nearly 60 others wounded. Blood and pieces of flesh littered the floor among overturned chairs at the scenes of the blasts, which went off as people watched the game between Spain and the Netherlands late Sunday. The attack on the rugby club, where crowds sat outside watching a large-screen TV, left 49 dead, police said. Fifteen others were killed in the explosion at an Ethiopian restaurant.
