Mali conflict: France says its troops now in Kidal

French forces say they have entered Kidal in the north of Mali, the last major town they have yet to secure in their drive against Islamist militants.

French forces now control Kidal airport after a number of aircraft, including helicopters, landed there overnight.

Islamist militants were reported to have already left the town and it was unclear who was in charge.

French and Malian forces have been sweeping north, earlier taking Gao and Timbuktu with almost no resistance.

France - the former colonial power in Mali - launched a military operation this month after Islamist militants appeared to be threatening the south, BBC reports.

France's Foreign Minister Laurent Fabius told the meeting impressive progress had been made but that this did not mean the danger was over.

Mr Fabius also said credible elections in Mali would be vital to achieving sustainable peace in the country.

Mali's interim President Dioncounda Traore said on Tuesday that he wanted to hold "transparent and credible" elections by 31 July.
