Two Ugandans have pleaded guilty to charges stemming from twin explosions that killed 76 people in the capital, Kampala, in July of last year.

Edris Nsubuga pleaded guilty to three counts of terrorism during a Ugandan High Court hearing Monday.

Muhamoud Mugisha admitted to one charge of conspiracy to commit acts of terrorism.

The duo were among 12 people who appeared before the court in Kampala. Together the suspects face dozens of charges related to the bomb attacks, including murder and terrorism.

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.

The group said the attack was revenge for Uganda's role in the African Union peacekeeping force that is helping the Somali government battle al-Shabab.

Al-Shabab is trying to seize power in Somalia and turn the country into an Islamic state. The Kampala bombings marked the first time the group carried out a major terror attack outside Somalia.
