The grieving parents of an 11-year-old girl whose suspected killing has sparked outrage in France over failures to protect children on Sunday joined thousands of people for a silent march in her memory.

The body of the girl, named as Lyhanna, was found last week after she went missing on May 29th near the southwestern town of Fleurance.

She was last seen getting into a man's car, and public anger grew after it emerged that the main suspect, who is now under arrest, had previously been accused of sexually abusing children.

A sea of people filled the streets of Fleurance under scorching afternoon heat for the march, which was attended by local representatives but, in line with the family's wishes, not by national politicians.

They marched in total silence, dressed in white shirts and some holding white flowers. Around 6,000 people were present, according to the local authorities.
