On the evening of June 1 local time, Israeli Prime Minister Netanyahu held a phone call with U.S. President Trump to discuss developments in Iran and Lebanon. The call followed Israeli forces crossing the Litani River to launch an offensive, effectively collapsing a temporary ceasefire that began April 17. On May 31 Netanyahu ordered an expansion of military operations in Lebanon and has sought U.S. support for strikes on Beirut and other targets, a request he has communicated to Washington.
