The conflict between Iran and Israel has dramatically escalated, with fresh explosions reported in both Tehran and Tel Aviv following Israel’s unprecedented airstrikes early Friday on Iranian nuclear and military targets.

The Israeli strikes reportedly killed several of Iran’s top military and nuclear officials, prompting Tehran to vow a “crushing response” to what it called an act of aggression.

In a warning to regional powers, a senior Iranian official told media that Iran will target any country’s military bases that support or defend Israel during this conflict.

Israeli Prime Minister Benjamin Netanyahu declared that “more is on the way,” signaling that further military action may be imminent.

Meanwhile, former U.S. President Donald Trump told media that the United States “of course” supports Israel and urged Iran to reach a nuclear agreement “before there is nothing left.”
