Israel has said that it is holding an employee of the French consulate in Jerusalem on suspicion of smuggling weapons from the Gaza Strip to the West Bank.
The French citizen, identified as Romain Franck, was arrested in mid-February but Israeli authorities only revealed the information on Monday after a gag order was lifted.
Franck is accused of smuggling a total of 70 pistols and two assault rifles, according to Israeli media reports.
Citing Israel's internal security agency - the Shin Bet - Israeli news outlets said the employee was acting out of financial motives.
He reportedly used a consular vehicle to collect the weapons from a Palestinian in the occupied Gaza Strip before bringing them to the occupied West Bank in five separate smuggling instances.
Several Palestinians have also been arrested in Jerusalem in suspicion of connection with the case.
Al Jazeera reached out to Palestinian authorities in the Gaza Strip and is yet to receive a comment.
According to Israeli daily newspaper Haaretz, the French consulate issued a statement saying: "The authorities in France are taking the incident in which one if the workers at the consulate general of France in Jerusalem is a suspect with very great seriousness. The authorities in France are cooperating with Israeli authorities."
Barak Ravid, an Israeli journalist for Channel 10, said the "incident was dealt with by the highest levels in both countries to prevent diplomatic crisis".
The French consulate handles diplomatic services to Palestinians in Jerusalem.
