In a shocking case of alleged negligence, Israeli security officials left confidential documents about the weapon deal with India at Tel Aviv's Ben Gurion Airport before boarding a flight to New Delhi in January, says a report. The delegation was headed by National Security Council Chief Meir Ben Shabbat.

According to a report in the Haaretz, a leading Israeli newspaper, Ben Shabbat and his team had dined at an airport restaurant before boarding the flight. It says Ben Shabbat's aide, who printed the classified documents, inadvertently left the papers at the eatery.

The report says a waiter at the restaurant found the papers on a table and realising their sensitivity he dialed a friend whose mother works for the Israeli embassy in India. The waiter's friend later took a flight to India and handed the paper over to his mother.

An investigation launched into this chain of incidents concluded that no dangerous entities were exposed to the contents of the documents.

"The incident was taken care of immediately, a security investigation was carried out and lessons were learned," the report quotes Israel Prime Minister’s Office as saying in response to their report.

In New Delhi, Ben Shabbat had held talks with Prime Minister Narendra Modi and other top officials.

Israel reportedly wants to boost its arms trade with India and wants to sell many of its advanced weapons including spy planes, unmanned aircraft, anti-tank missiles, cannons and radar systems.
