US Central Command (Centcom) said on Monday that American forces launched “self-defence” strikes targeting Iranian missile sites and boats allegedly attempting to place mines near the Strait of Hormuz.They reportedly struck areas near Bandar Abbas, an important Iranian port city located along the Strait of Hormuz.Tehran condemned the attacks and said they violated the ceasefire arrangement. Iran’s IRGC later claimed to have downed a US drone and fired at an American fighter jet and another drone that entered Iranian airspace. The military body also said Iran had the “legitimate and definite” right to respond to any US ceasefire violations.US-Israeli war on IranThe US and Israel bombed Iran on February 28 and assassinated their Supreme Leader and many top officials. This led to retaliatory strikes by Tehran on Israel and US bases on the Gulf.Iran also effectively closed the Strait of Hormuz which disrupted shipping routes and caused global oil prices to rise sharply.Although a ceasefire has largely held since April 8, tensions have continued in and around the Gulf region.The proposed MoU reportedly includes extending the ceasefire, reopening the Strait of Hormuz and holding further negotiations on Iran’s nuclear programme. The nuclear issue remains one of the biggest sticking points in talks between Washington and Tehran.
