New Delhiinfo-icon: In a shocking case of alleged negligence, Israeli security officials left confidential documents about the weapon deal with Indiainfo-icon at Tel Aviv's Ben Gurion Airport before boarding a flight to New Delhi in January, an Israeli newspoaper reported on Thursday. 

The delegation, according to the Haaretz newspaper, was headed by National Security Council Chief Meir Ben Shabbat.  

Shabbat and his team, was en route to New Delhi in January when they dined in an airport restaurant. A member of the delegation then, however, left a folder there with top-secret material, Haaretz report said.

The report added that a waiter at the restaurant found the papers as the delegation was already in the air on its way to India.

He leafed through the documents, realizing their sensitivity and the fact that they were related to India.

The waiter reportedly called a friend, whose mother works for the Israeli embassy in India.

The friend flew to India and handed the file to her mother, who gave it to the embassy's head of security, who then reported the incident back to Israelinfo-icon.

Following the events and at the directive of Israel's National Security Council chair Yoav Horowitz, the council launched an investigation into the incident. The probe asserted that the loss of the documents had not damaged Israel's interests. 

Ben Shabbat's aide was subsequently accused of losing the sensitive material, and he was placed under warning.

Israel wishes to sell India several advanced weaponry, including stealth aircraft, unmanned aerial vehicles, anti-tank missiles, cannons and radar systems. 

India is currently the biggest buyer of Israeli military hardware, spending an average $1 billion annually on military equipment in recent years.

In July 2017, Narendra Modi became the first Indian prime minister to visit Israel, weeks after New Delhi and Tel Aviv signed a two-billion-dollar military deal.

In the past decade, India has reportedly bought more than $10 billion worth of arms from Israel.
