Cease-fire between Somalia's Puntland and Galmudug collapses, 20 killed

A week-old cease-fire between the forces of two semi-autonomous regions of Somalia broke down on Sunday as fighting over a disputed border area erupted again, killing at least 20 people, army officials on both sides said.
Galmudug and Puntland are clashing in the town of Galkayo, which straddles their common border and is divided under the control of rival clan militias. As violence between these groups began to escalate a month ago, schools in Galkayo were forced to close and some people fled the town.
Under terms of a cease-fire deal mediated by Dubai and which was welcomed by the two sides and Somalia's federal president, forces of both regions were supposed to be withdrawn from the disputed area this past week.
