The secrets Trump gave Russia reportedly came from Israel, whose spies are not happy

Reports that Israel was the source of highly classified information that US President Donald Trump shared with Russian officials last week have sent a chill through current and former Israeli intelligence officials.
Israeli intelligence officers are taking the matter seriously, a military intelligence officer said Tuesday. The officer, who asked not to be identified because he was not authorised to speak publicly, said Israel was warned months ago to be careful about sharing information with Trump’s staff, and now that warning has been realised.

The intelligence referred to Islamic State “terrorism and airline flight safety” that could impact both the US and Russia, Trump said in a pair of tweets Tuesday.
Israel’s vaunted intelligence service, known for an extensive network of human sources and technical collection throughout the Middle East, regularly shares detailed information with the United States, its closest ally.
