US forces attacked radar sites on Iran’s coast, the US military said in the latest flare-up to threaten the ceasefire in the Mideast war.

US Central Command said in a statement that US forces shot down four Iranian one-way attack drones launched toward the Strait of Hormuz, then attacked Iranian coastal surveillance radar sites in the city of Goruk and on Qeshm Island.

The US command said the drones posed an immediate threat to maritime traffic.
