JERUSALEM, March 4 (Xinhua) -- The Israeli military said on Wednesday that it is "continuing to deepen" its attacks across Iran, revealing that it has dropped more than 5,000 munitions on the country since the joint U.S.-Israeli operation began on Saturday.

The military said the airstrikes now focus mainly on government targets in Tehran.

Earlier on Wednesday, Iran said 1,045 people had been killed in the country since Saturday as a result of the U.S.-Israeli operation.

Meanwhile, according to Israel's Magen David Adom rescue service, Iranian missiles have killed at least 10 people in Israel.

The joint U.S.-Israeli military operation against Iran, entering its fifth day, has triggered a sharp escalation across the Middle East, setting off waves of missile exchanges, mounting casualties, and far-reaching political, security, and economic repercussions. ■
