Al-Shabab Declares Kenya an 'Official War Zone'

Al-Shabab terrorists in Kenya killed nine more people overnight Tuesday in the same Kenyan coastal area where the Somali militant group slaughtered 48 people Sunday night.

The Islamist group said the attack was in response to Kenya's "brutal oppression of Muslims in Kenya."

Witnesses say the gunmen singled out non-Muslims during the attack, going door to door demanding to know if the men inside were Muslim and if they spoke Somali.

The merciless tactics were reminiscent of al-Shabab's attack on an upscale mall in Kenya's capital city of Nairobi last September. At least 67 people were killed in that assault, some of them after not being able to answer questions about Islam.

Al-Shabab is warning tourists to stay away from Kenya, saying that the once peaceful east Africa nation "is now officially a war zone."
