The ceasefire between the US and Iran lasted about two months before it stopped being a ceasefire. Military forces from both nations exchanged strikes on June 10 and June 11, 2026, marking two consecutive days of hostilities that have effectively shattered the truce agreed upon on April 8.

What was supposed to be a two-week pause in fighting, later extended through diplomatic channels, now looks like little more than a breather between rounds.

What happened and why it matters

The latest flare-up traces back to an incident near the Strait of Hormuz, one of the most strategically important chokepoints for global oil supply. US airstrikes targeted Iranian cities following a helicopter incident in the strait, and Iran responded with retaliatory strikes affecting neighboring Gulf states, including Bahrain and Kuwait.

The broader conflict kicked off on February 28, 2026, when US-Israel military actions against Iran set off a chain of escalating confrontations. The April ceasefire was meant to cool things down, but skirmishes had already resumed by early May.
