After Kampala attack, Somali militants promise more operations

Al-Shabaab, the Somali militant group that claimed responsibility for Sunday's deadly attacks in Uganda, is promising to "unleash a new tide of terror," but Uganda's leader has vowed to "deal with the authors of this crime and fight back. This is only the beginning," Al-Shabaab warned Thursday in a statement on the internet. Al-Shabaab claimed responsibility for the bombings that killed 76 people in two locations in the Ugandan capital of Kampala. The attackers struck an Ethiopian restaurant in a neighborhood dotted with bars and popular among expatriates. Two other bombs exploded at a rugby center. Police in Uganda have reported arrests in connection with the bombings, which also wounded dozens of people. Al-Shabaab had said it is waging war "against 6,000 collaborators," a reference to the African Union peacekeeping force that includes Ugandan troops and warned Ugandans to refrain from involvement in Somalia. Burundi is a main troop contributor nation, and it has been threatened, too.
