The Israel Defense Forces (IDF) said they intercepted most of a barrage of rockets Hamas and other Iran-backed groups fired toward Tel Aviv, as fighting escalated Monday on multiple fronts after a year of war.

Sirens sounded across central Israel, and two people were injured, according to Israeli health officials.

The military had earlier warned of what it called an ¡°immediate¡± threat of rocket fire from Hamas to mark the militant group¡¯s attack on the country 12 months ago.
