Hayat Boumeddiene, the wanted partner of one of the gunmen shot dead by police after three days of high drama in France, arrived in Turkey before the killings and may now be in Syria, a Turkish security source told AFP.
"She entered Turkey on January 2," the source said, adding that she was believed to have moved on to the southeastern Turkish city of Sanliurfa and then to Syria but there was "no concrete data" to prove it.
The source said Turkey did not arrest her because of a lack of intelligence from France. "We do not have the luxury to prevent everyone entering without intelligence sharing," the source said.
