A Ugandan judge has sentenced two men for their part in twin bombings that killed 76 people in Kampala last July.

The Somali insurgent group al-Shabab claimed responsibility for the suicide bombings, which targeted a group of people who had gathered to watch the 2010 World Cup final.

On Friday, the judge sentenced Edris Nsubuga to 25 years in prison on terrorism charges. Muhamoud Mugisha received a five-year sentence for conspiracy to commit terrorism. Both men had entered guilty pleas earlier this week.

Prosecutors have said they will call both men to testify in the upcoming trials of 12 other suspects in the Kampala bombings.

Al-Shabab said the attack was revenge against Uganda, for the Kampala government's role in the African Union peacekeeping force backing the Somali government in its fight against Islamic extremists trying to seize power in Mogadishu.

The Kampala bombings marked the first time al-Shabab carried out a major terror attack outside Somalia.
