An offensive by pro-Somali government troops and Ethiopian forces against Al-Shabab militants in the western Somali town of Bulo Hawo has forced thousands of people to flee their homes there and in the nearby Kenyan town of Mandera, say witnesses and officials. One resident of Bulo Hawo, normally home to some 60,000 people, and also close to the Ethiopian border, said much of the now nearly deserted town had been destroyed 'after days of shelling'.
