JERUSALEM — A Frenchman working at his country’s consulate in Jerusalem was charged on Monday with smuggling guns into the West Bank from Gaza, as Israelis braced for more violence in the Palestinian territories after two deadly attacks and the destruction of two border tunnels over the weekend.

Israel’s internal security service, the Shin Bet, said that Romain Franck, a French citizen, had “cynically exploited” lenient scrutiny of diplomatic vehicles to smuggle 70 pistols and two assault rifles on five trips from Gaza through the Erez crossing.

Mr. Franck, 24, obtained the weapons from a Gaza man employed at the French cultural center there, drove them into Israel — the Shin Bet released a photo of an S.U.V. it said Mr. Franck had used — and then delivered them to the West Bank, where they were sold to illegal arms dealers, the security service said.

Eight others were also arrested in connection with the smuggling operation, including a Palestinian resident of East Jerusalem who works as a security guard at the French Consulate.
