The government said Friday its security forces killed 72 of about 400 cattle rustlers who raided its territory from neighboring Uganda.

In a protest note handed to Uganda's acting ambassador in Nairobi, the government demanded an explanation for the raid, which it said was carried out by heavily armed men.The Ministry of Foreign Affairs said the raiders, some wearing military uniforms, were discovered Thursday by a Kenyan security force.

Two Kenyan security officers were killed and a resident was injured in the gunbattle near Pokot, a small village in northwestern Kenya, the ministry said.
