Hezbollah has threatened to wage a war on Israel if the IDF attacks the Iran-backed group first. Hezbollah's second-in-command, Naim Qassem, said, "If Israel attacks us and aggresses us, then we will definitely respond. If they escalate, we will escalate." The fresh threat comes amid heightened tensions between Israel and Iran in the Middle East. Early morning, explosions were heard in Iran's Isfahan province. U.S. officials claim that they were heard due to Israel's retaliatory missile strikes on Iran to avenge the weekend missile and drone barrage from Tehran. However, there has been no official confirmation. Watch. INTERNATIONAL NEWS
