Turkey reportedly had alerted French intelligence agencies twice about Ismael Omar Mostefai - first after he joined Isis in Syria in 2014 and later in 2015.

The statement from a Turkish official has come at a time when France is facing increased scrutiny over intelligence failure that eventually led to the attacks that left at least 130 people dead and about 300 injured at six locations in Paris.

The Turkish official told Reuters that Ankara had alerted France in December 2014 and in June 2015 about Ismael Omar Mostefai, one of the suicide bombers responsible for the Paris attacks on Friday (13 November, 2015).

Mostefai, 29, from Chartres, southwest of Paris, was identified by the police based on his fingerprints from his finger that was severed after he detonated his suicide vest.

The agency said that the Turkish official revealed that despite twice providing information about the French Isis jihadi, it heard back from the authorities in France only after the deadly attacks on Friday.

In the wake of the attacks, French intelligence officials are being blamed for the security lapse. 

Meanwhile, according to a report in the Israeli newspaper, Ynet News, France had received a warning "two weeks" before the 13 November attack of an increase in communication between Isis elements in the Middle East and their affiliates in France.

However, the security agencies followed routine protocol and increased security measures at foreign embassies and high-value targets, the report noted.

Yves Trotignon, a former counter-terrorism official in the French external service, DGSE, however, told The Guardian that to remain in high alert for such attacks is difficult as there are several potential targets.

"It is extremely difficult to defend against such an attack once it has begun to be executed," Trotignon said. "We have seen that not only in Mumbai, but also in Nairobi and Peshawar."
