Iran and the US have traded attacks in the Gulf, raising fears that the fragile ceasefire between the two countries is unravelling, Al Jazeera reports.

Iran’s Islamic Revolutionary Guard Corps (IRGC) said Saturday they had hit US sites in the Gulf in retaliation for US attacks on Iranian missile, drone and radar facilities – themselves a response to what Washington said was an Iranian drone attack on a cargo ship in the Strait of Hormuz.

US Central Command (CENTCOM) said the latest US attacks, against Iranian missile and drone storage sites and coastal radar positions, were a response to “unwarranted aggression against commercial shipping by Iranian forces” that “clearly violated the ceasefire”.
