More than 3,000 Iranians were reported to have been killed in the conflict. Israel says 26 Israelis have been killed. Thousands of people in both countries have been injured. The U.S. military says 13 of its members have been killed. Israel renewed attacks on Lebanon on March 18 as part of the wider war, and about 3,700 people have been killed there, according to Lebanon’s health ministry.
Strikes, mainly by Iran, have also killed people across the Middle East, including workers from South Asian countries in the Persian Gulf.
