(CNN) -- 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.
