A Kenyan military spokesman says Kenyan soldiers stopped a terror attack by killing five suspected Islamic extremist bombers attempting to cross into Kenya from Ethiopia in a car carrying explosives and six suicide vests.

Bogita Ongeri said Sunday authorities recovered 100 kilograms (220 pounds) of TNT from the vehicle which was intercepted at Dolo along Kenya's border with Ethiopia on Saturday.

Ongeri said security forces had been tracking the car which had Kenyan registration and were aware that the suspected terrorists had unsuccessfully tried to gain entry into Kenya at another border point. He said the five suspects killed are members of the Somali militant group al-Shabab, which is allied to al-Qaida. Al-Shabab carries out terrorist bombings in Kenya because Kenyan troops are in Somalia fighting the militants.
