CRI听力:Paris Attack Suspect Crosses into Syria from Turkey

Surveillance video appears to show the female accomplice of one of the Islamist militants behind the recent attacks in Paris crossing into Turkey five days before the killings.

Turkish authorities say 26-year-old Hayat Boumeddiene arrived in Istanbul from Madrid on January 2 and crossed into Syria six days later.

Interior Minister Efkan Ala says Turkey had received no request from Paris to deny her access.

"There was no notice from France on this person stating that she is dangerous and she should be banned from entering the country. Therefore, there isn't a specific entry ban on this person."

French police are seeking Boumeddiene after her partner Amedy Coulibaly was killed in a raid on a Jewish supermarket where he had taken hostages.

There was some confusion at first about whether she had been present in the supermarket when police stormed it, and had escaped.

Back in France, about 10,000 troops have been deployed in the country to protect sensitive sites following last week's terror attacks that left 17 people dead.

It is the first time troops have been deployed within France on such a scale.

Nearly half of them will be assigned to protect over 700 Jewish schools across the country.

French Interior Minister Bernard Cazeneuve visited several Jewish schools in Paris, describing the security measures as "exceptional."

"As interior minister, I cannot accept that some parents are scared to send their children to schools because they could be threatened."

Security has also been stepped up around synagogues and mosques, following some retaliatory attacks over the Charlie Hebdo killings.

According to the Central Council of Muslims in France, there had been more than 20 attacks on Islamic buildings and 30 threats against Muslims since Wednesday when the violence started.
