Iran said it fired dozens of missiles into Israel on Tuesday, a sharp escalation of the monthslong conflict between Israel and the Iran-backed militias Hezbollah and Hamas. There were no immediate reports of casualties as Israel ordered residents to head to bomb shelters and as air raid sirens sounded across the country.

The Israeli military official said Hezbollah had launched rockets at central Israel, setting off air raid sirens and wounding a man. Hezbollah said it fired salvos of a new kind of medium-range missile at the headquarters of two Israeli intelligence agencies near Tel Aviv.
