The attack that took place earlier today is the second by al-Shabab after the bloody four-day standoff at the Westgate Mall that ended Tuesday in which at least 67 people were killed.
Al-Shabab threatened in a message yesterday that if the Kenyan troops remain in Somalia, Kenyans must "be prepared for an abundance of blood."
Regional police chief Charlton Mureithi says the militants' attack in the town of Mandera also resulted in three police officers injured and 11 vehicles destroyed.
