Ugandans on Monday marked the anniversary of a double suicide bomb attack in Uganda's capital that killed 76 people who had gathered to watch the World Cup final.

Survivors and relatives gathered at a Kampala rugby club where one of the bombs went off.

Ugandan police last week issued a terror alert saying they received fresh threats from the Al-Shabab militant group, Somalia's most dangerous militant group, which has ties to Al-Qaeda.

Uganda is a major contributor to the African Union peacekeeping mission in Somalia, which supports Somalia's weak government in its fight against Al-Shabab.
