President Donald Trump was “caught off guard” by Israel’s bombing of Syria, the White House said Monday, amid reports that the US president was increasingly concerned by Israeli Prime Minister Benjamin Netanyahu’s aggressive military efforts.

An Israeli strike last week hit a Catholic church in Gaza, and also bombarded Syria during sectarian violence there. The comments were a rare suggestion of daylight between Trump and Netanyahu.

President Donald Trump was caught by surprise last week by Israeli actions in Gaza and Syria, and in both instances phoned Prime Minister Benjamin Netanyahu to “rectify” the matter, according to the White House.
