Change of US position on free navigation comes as two tankers hit by Iranian cruise missiles

Good morning. The US has launched its third consecutive night of strikes on Iran, hours after Donald Trump said Washington would reinstate a maritime blockade on the country and charge ships for safe passage. The UAE said two ⁠national tankers ⁠were ​targeted by two Iranian cruise missiles in ⁠the southern lane of the strait ⁠of Hormuz in Omani territorial ​waters, ‌killing one ‌Indian crew member and wounding ‌eight others, including four seriously.

Iran and the US are in theory nearly halfway through the 60-day period of an interim deal that was supposed to set up talks for a permanent end to the war, which began in February with the assassination of Iran’s supreme leader, Ali Khamenei. In reality, that deal has devolved into a series of attacks over the strait of Hormuz, resulting in the near-total collapse of an interim ceasefire and worrying world leaders that the conflict could fully resume.

Lindsey Graham’s sister appointed to serve rest of Republican’s Senate term

Rubio launches campaign to dismantle international criminal court

Marco Rubio, the US secretary of state, launched a campaign to dismantle the international criminal court (ICC) on Monday, claiming the global tribunal was interfering with US military and law enforcement operations at the risk of American sovereignty. Rubio invoked images of US border patrol agents and elected leaders being “dragged before an international court” and tried by judges from around the world.

“If we stand idle, all of them will be at the mercy of foreign judges, thousands of miles away – facing the constant risk of prosecution and even imprisonment for the so-called ‘crime’ of defending their own country,” Rubio said in a video.

Don’t miss this: Sale of multimillion-dollar T rex skeleton is big headache for scientists

One of the largest and most complete T rex skeletons discovered to date is to be auctioned by Sotheby’s in New York with an estimated sale price of $20m-$30m – and scientists are worried about the trend. Prof Richard Butler, a vertebrate paleontologist at the University of Birmingham in the UK, said: “Dinosaur fossils being marketed and sold like rare artworks at vast prices by auction houses is very concerning. A fossil not in a recognised museum collection cannot be studied and is therefore lost to research.”
