What happened

Israel and Iran have returned to active war for the first time since a ceasefire was agreed two months ago in an exchange of rocket fire that threatened efforts to end the conflict.

Why it matters

Donald Trump, who started the war in February alongside Israel but has since attempted to present himself as a mediator, told the two sides to stop shooting and said “final negotiations” on peace were proceeding.

Common ground

By late afternoon on Monday, the attacks had stopped.

Perspective signals

The tension in the story is sharpened by Loaded Language, Causal Oversimplification: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
