After deadly Al Shabab attack, questions about Kenya's approach

(The Christian Science Monitor) The militant Islamist group Al Shabab attacked a bus in northeastern Kenya Saturday and murdered the 28 non-Muslim passengers on board.

Al Shabab said the attack was retaliation for police raids on mosques in the coastal city of Mombasa, which included the arrest of hundreds of young Muslim men and the temporary shutdown of four mosques there. The Kenyan Defense Forces responded to Saturday’s attack by destroying the camp in Somalia from which it was launched.

The bus attack is a reminder that the government’s heavy-handed tactics haven't worked. Al Shabab has only become more active in Kenya since Kenyan troops fought the group in Somalia in 2011.
