Family and friends have joined a march of some 10,000 people through a French town in response to the murder of a local woman who vanished last weekend.

The burnt body of Alexia Daval, 29, who disappeared while jogging, was found in woodland near Gray, a town in the north-eastern region of Haute-Saone.

An autopsy has found she was strangled. No arrests have been made and her attacker's identity remains unknown.

Women have honoured her with symbolic runs in cities across France.

In Gray, a quiet town of 5,000 residents, people marched in silence on Sunday and listened to speeches by her grieving husband Jonathan Daval and other family members.

Mrs Daval, a bank worker, went out for a run on Saturday 28 October. After not hearing from her for several hours, her husband called the police.

Her body was eventually found covered in foliage in a wood far from her normal jogging route.

A source close to the investigation told AFP news agency there were no preliminary indications she had been raped.
