Israel hit bases and nuclear sites in a stunning assault that went beyond past attacks on Iran. President Trump warned Tehran to agree to new limits on its nuclear program because further strikes could be “even more brutal.”

Residents of Tehran, the Iranian capital, reported hearing huge explosions and Iranian state television broadcast images of smoke and fire billowing from buildings.

Israel’s military struck Tehran and other targets early Friday morning, raising fears of a broader war. The U.S. said it was not involved in the strikes.
