The death toll from bombings in Uganda rose to at least 74, authorities said Monday, a day after explosions ripped through two venues where crowds were watching the World Cup.

At least 71 people were hospitalized, police spokeswoman Judith Nabakooba said.

The blasts hit in the capital, Kampala, within 50 minutes of each other. The first one struck an Ethiopian restaurant in a neighborhood dotted with bars and popular among expatriates; two others exploded at the rugby center.

A senior Ugandan government official confirmed there were three bombs. The second one at the rugby club was the most severe, said the official, who is not authorized to speak to the media because of the sensitivity of the situation.

Immediate suspicion swirled around Somalia Islamist groups. Islamic militants battling Somalia’s U.N.-backed transitional government have threatened attacks on Uganda and Burundi, which contribute troops to an African Union peacekeeping mission in Somalia.
