A suspected would-be suicide bomber was one of four people arrested in the southern French city of Montpellier by anti-terrorist police.
Home-made explosives similar to those used in the Paris attacks of November 2015 were also discovered, police and judicial sources said.
A girl of 16 was arrested along with three young men.
Since the beginning of 2015, at least 230 people have been killed in jihadist attacks in France.
Last month, a soldier received minor injuries when a machete-wielding man tried to enter the Louvre museum in Paris.
The man, a 29-year-old Egyptian named as Abdullah Hamamy, was shot and critically injured.
The four suspects in Montpellier were arrested after buying acetone, a police source told AFP news agency. Acetone is an ingredient used in the making of triacetone triperoxide (TATP), a high explosive.
TATP, the same explosive used in bomb vests worn by militants in the Paris attacks, was found in the city along with the acetone, a judicial source said.
According to AFP, the female suspect had been spotted on social networks saying she wanted to leave for the Syria-Iraq conflict zone or mount an attack in France instead.
Meanwhile, the country's top constitutional court struck down a law which penalised those who consult jihadist websites.
The Constitutional Council found that the law infringed on people's freedom of communication unnecessarily.
