President Donald Trump warned on Monday that Iran's energy plants and oil wells would be obliterated if it did not open the Strait of Hormuz, after Tehran described US peace proposals as "unrealistic" and fired waves of missiles at Israel, Reuters reported. 

Israel's military said two drones from Yemen had also been intercepted on Monday, two days after the Iran-aligned Houthis entered the war by firing missiles at Israel, and that Lebanon's Hezbollah had fired rockets at Israel.

Israeli forces carried out missile strikes on what they called military infrastructure in Tehran and infrastructure used by Iran-backed Hezbollah in Beirut, leaving black smoke hanging over the Lebanese capital.
