Photos of two suspects of the Kampala bombings have been released by the international police agency Interpol.

Investigators in Uganda say they believe the attacks were the work of suicide bombers. The bodies "have remained unclaimed and unidentified," a Ugandan police chief said.

The Interpol team, which was called in by Ugandan police to help with the investigation, put together the reconstructions from remains found at the scene.

The  facial reconstructions of the suspected attackers suggest one was of Somali origin and the other a black African of undetermined origin.

After lasts week's deadly blasts in Kampala Ugandan police has arrested at least 20 people, including several Pakistanis.

One of the arrested Pakistanis had been mentioned in an email sent by a presumed Shebaab spokesman as having links with the Islamist group, the police chief said.

"By making these photos public, we believe someone, somewhere could recognise one or both of these men," Interpol quoted Kayihura as saying as it released the photos.

"Our investigation into these terrible acts is advancing, and publishing these photos is another step forward in finding those responsible for the death and injury of so many innocent victims," he added.

Police said a suicide vest laden with explosives and fitted with a detonator was found packed into a black laptop bag at a disco in Kampala a day after the blasts.
