Security forces have arrested more than 20 people, including five Pakistanis, for two bombings last week that killed at least 73 people in the Ugandan capital, the police chief said today.
"In terms of those who are in custody, certainly it is more than 20," Kale Kayihura told reporters.
Among them were five Pakistanis who had a shop in a Kampala suburb, Kayihura said. "They are being questioned, they have to explain themselves," the police chief said.
The July 11 bombings at a restaurant and a crowded bar where people were watching the football World Cup final held in South Africa were claimed by the Al-Qaeda-inspired Shebab insurgent group in Somalia.
One of the Pakistanis had been mentioned in an email sent by a presumed Shebab spokesman as having links with the Islamist group, the police chief said.
The Shebab said the attacks were in retaliation for the presence of Ugandan troops in an African Union force in Somalia, propping up the fragile Western-backed transitional government.
He also said they believe that two suicide bombers took part in the attacks.
Facial reconstructions of the two suspected suicide bombers suggest that one was of Somali origin and the other a black African of undetermined origin, he said.
"There is strong evidence that these attacks were carried out by suicide bombers," Kayihura said. He said the facial reconstructions had been carried out on two bodies which "have remained unclaimed and unidentified."
The July 11 bombings in Kampala were claimed by Al Qaeda-inspired Shebab rebels in Somalia.
