Trump threatens to strike Iran over support for Hezbollah as fighting continues in Lebanon

US President Donald Trump on Sunday threatened to strike Iran if it did not stop Hezbollah from "causing trouble," as peace talks between senior US and Iranian officials began in Switzerland. The memorandum of understanding signed Wednesday between the United States and Iran stipulates a cessation of hostilities on all fronts, including in Lebanon. But Israeli strikes on Lebanon continued -- in response, they say, to projectiles fired by the Iran-backed group at its troops.
