House-to-house searches

France, however, appeared to have assumed control of the operation on the ground. Its airstrikes allowed Malian troops to drive the Islamists out of the town of Konna, which they had briefly seized this week in their southward advance.

Calm returned to the town on Sunday after three nights of combat as the Malian army mopped up any rebel fighters. A senior Malian army official said more than 100 rebels had been killed.

"Soldiers are patrolling the streets and have encircled the town," one resident, Madame Coulibaly, told Reuters by phone. "They are searching houses for arms or hidden Islamists."

Human Rights Watch said at least 11 civilians, including three children, had been killed in the fighting.

A spokesman for Doctors Without Borders in neighbouring Mauritania said about 200 Malian refugees had already fled across the border to a camp at Fassala and more were on their way.

In Bamako, civilians tried to contribute to the war effort.

"We are very proud and relieved that the army was able to drive the jihadists out of Konna. We hope it will not end there, that is why I'm helping in my own way," said civil servant Ibrahima Kalossi, 32, one of over 40 people who queued to donate blood for wounded soldiers.
