Iran live updates: Trump threatens Iran infrastructure strikes if talks fail

Israel Defense Forces spokesperson Lt. Col. Nadav Shoshani told a press briefing on Sunday that strikes on Iranian weapon production and nuclear facilities are now the priority of IDF operations.

Shosahni said that on Saturday, Iran fired fewer than 10 ballistic missiles toward Israel while Hezbollah launched dozens of drones and rockets from Lebanon. Shosahni said that 90% of Saturday's attacks were intercepted.

Shoshani described the IDF ground operation inside southern Lebanon as "defensive," although Israeli officials have said their forces intend to seize additional Lebanese territory as a "buffer zone" to protect northern Israel from Hezbollah fire. Shosahni said that 850 Hezbollah members -- many from the elite Radwan Force -- have been killed in recent clashes.

Shoshani defended the IDF's Saturday killing of journalist Ali Shuaib, who he claimed -- without providing any evidence -- was a member of the Radwan Force. Shosani did not comment on the killing of two other Lebanese journalists -- Fatima Ftouni and Mohamed Ftouni -- on Saturday.
