The life of a spy supplying information to Israel from inside Daesh may be in danger after US President Donald Trump shared highly classified intelligence with the Russians, according to American media reports.

The agent told the Israelis about a Daesh plan to explode a bomb on a plane flying to the US, according to ABC News. This information was reportedly behind a recent US and UK ban on travellers on flights from certain Middle Eastern countries taking laptops in their cabin luggage. The US is reportedly considering demanding the same ban apply on flights from Europe.

US officials confirmed to CNN that Israel was the source of at least part of the information on the capability of Daesh bomb-making which Mr Trump shared with Sergey Lavrov, the Russian Foreign Minister, and Sergey Kislyak, the Russian ambassador to the US.

The White House has refused to comment on the source of the intelligence information, but Mr Trump has not denied sharing it. He tweeted on Tuesday that: “As President I wanted to share with Russia (at an openly scheduled WH meeting), which I have the absolute right to do, facts pertaining to terrorism and airline flight safety. Humanitarian reasons, plus I want Russia to greatly step up their fight against ISIS & terrorism”.

Dan Shapiro, the former US ambassador to Israel, described Mr Trump and his team as “careless”, warning ABC that such actions would “inevitably cause elements of Israel's intelligence service to demonstrate more caution” before sharing information with the Americans.

However, Israel’s ambassador to the United States, Ron Dermer, was at pains to stress that the country’s ties with the US had not been damaged, ahead of Mr Trump’s visit to Israel next week.

"Israel has full confidence in our intelligence-sharing relationship with the United States and looks forward to deepening that relationship in the years ahead under President Trump”, Ambassador Dermer said.
