Afghan security forces are back in control of the strategic northern city of Kunduz, Nato forces and local police say. Taliban fighters earlier appeared to have breached the city, reportedly raising their flag in a central square. <br/><br/>In a major victory, Kunduz was briefly captured by the Taliban in September 2015 but government forces, backed by Nato, recaptured it within days. Special forces have been flown in from Kabul to help repel the latest assault.<br/><br/>The Nato-led Resolute Support mission said Afghan security forces were in control of the city and its main square with additional troops coming. Fighting is continuing near the city's Police headquarters, Governor's compound and National Directorate of Security headquarters. The Pentagon has suggested the assault was less serious than it may have appeared.<br/><br/>According to Afghanistan's Interior Ministry, at least one policeman was killed and four wounded in yesterday's fighting. The fighting comes a day before a major donors' conference in Brussels and highlights the precarious security situation after Nato pulled out combat forces.
