KAMPALA, July 12 (Xinhua) -- More than 40 people are feared dead after two bomb explosions rocked Kampala, Uganda's capital, on Sunday night, according to a local official.

"Over 40 people could have been killed in the blasts," said Moses Sakira, deputy director of Criminal Investigation Department. He said almost all of the victims were adults.

Uganda's New Vision website put the death toll at at least 33.

"We cannot rule out the terrorist attack possibility now," said Sakira. "It might be possible."

The Somali militia warned to launch attacks targeting civilians in Uganda, which had sent peacekeeping troops to the war-battered Somalia.

But the country's army spokesman Felix Kulayigye said it is still too early to know whether Somali militia were behind the bomb attacks as security forces just started the investigation at the scene.

According to the New Vision website, one explosion targeted the Kyadondo Rugby Club. The blasts occurred minutes after 11 p.m..

Blood, broken chairs, clothes and shoes were seen on the ground at the scene. Security soldiers and rescuers were evacuating and saving the wounded.

The scene has been cordoned off.

A witness who gave his name as Klaus told Xinhua that hundreds of local people were watching the World Cup final in front of a big projector at the club as the blast occurred.

The other blast was reported at the Ethiopian village, in the Kabalagala. The New Vision said a third blast was reported in Ntinda, which the local police did not confirm.
