WASHINGTON — President Donald Trump tried to keep a fragile ceasefire between Israel and Iran in place Tuesday as reports emerged indicating the U.S. attack on Iran's nuclear facilities over the weekend was not as successful as he initially claimed.

President Donald Trump called Israeli Prime Minister Benjamin Netanyahu on Tuesday and asked him not to send an immediate military strike in response to what Israel said was Iran’s violation of the ceasefire, said a person familiar with the exchange, who spoke on the condition of anonymity in order to discuss sensitive communications.
