Canada says it has come under economic attack from the US

The Canadian prime minister, Mark Carney, has said the trade war with the United States isn't Canada's choice, but his country is ready to retaliate. Talks between the neighbours collapsed late on Friday, with each accusing the other of seeking last-minute changes to a proposed trade deal. Also, the editor-in-chief of the US military newspaper, Stars and Stripes, raises concerns over censorship after he was dismissed by the Department of Defense for "insubordination". South Korea is sending a commercial vessel on a trial voyage to Europe via the Arctic in an effort to find alternative shipping routes because of war in the Middle East. Scientists in the US say that fish skin beats man-made products when treating people with severe burn injuries. And a humanoid robot has broken the men's world record for the 100-metre sprint set by Usain Bolt 17 years ago.
