The Pentagon is increasingly concerned about Israel ramping up its spying on the US, recently raising the counterintelligence threat level from America’s top ally in the Middle East to the highest level, according to NBC News.

The Pentagon’s Defense Intelligence Agency (DIA) in recent weeks issued the new counterintelligence threat assessment amid rising tensions between Israel and the US over the way forward in the war with Iran, the report said, citing o two US officials and one former US official.

“They said the DIA posted an internal message, viewed by one of the current officials, that raised the level for Israel to ‘critical’,” the publication said.
