Three men who tried to force their way into a British Army training camp in Kenya just after a terror attack at a US base have been arrested. The incident happened on Sunday just after a member of the US military and two contractors were killed after an attack by Somalia’s Al Shabab terrorist group on a military base in Kenya. The internal police report seen by <em>The Associated Press</em> says the three "terrorist suspects" were arrested on Sunday after trying to enter the British Army Training Unit in Laikipia county. It occurred around the same time as the Al Shabab assault on the US base in Lamu county. The British government was not immediately available for comment. Al Shabab's assault at the Manda Bay Airfield lasted several hours and destroyed several US aircraft and vehicles. The airfield is adjacent to Camp Simba, a key Kenyan military base used by US counter-terror forces. No Kenyans died in the attack, Kenya's military spokesman Paul Njuguna said on Monday. Al Shabab, which is linked to Al Qaida, has vowed retribution on Kenya for its troop presence in Somalia to counter the extremist group. The US base attack also left two military personnel wounded and destroyed several American aircraft and vehicles.
