Military troops were Wednesday clashing with insurgents who seized government buildings in northern Iraq, said security officials. At least five soldiers were killed in the fighting in the town of Suleiman Beik, some 170 kilometres north of the capital Baghdad, according to Shalal Abdul, a local police chief. "A number of insurgents have also been killed and injured in the clashes. But their specific number is not known yet," he told the independent broadcaster Alsumaria TV. The identity of the gunmen remains unclear, according to a report of DPA.
