Two people were killed and 26 injured in an explosion at a bus depot in Nairobi, Kenya, as passengers were preparing to board a coach.
Police say the blast happened on Monday as passengers passed through a security checkpoint before boarding a coach bound for Kampala, the capital of neighbouring Uganda.
One of those killed is believed to have been a passenger carrying a bag that contained a bomb.
The Red Cross says most of the wounded were Ugandans travelling home for Christmas.
Last July the al Shabab group in Somalia said it was behind an explosion in Kampala that killed more than 70 people.
The group also warned of more attacks as long as foreign peacekeepers remained in Somalia.
