Stock markets in Asia and Europe have reacted negatively to President Trump's announcement of tariffs against Canada, Mexico and China. From Tuesday, a 25% import tax will hit Canadian and Mexican goods entering the US, with 10% on Chinese goods, in addition to existing tariffs. It marks the escalation of a trade war that Trump has anticipated throughout his presidential campaign, citing border security, inflows of drugs and trade deficits as reasons for the restrictions. The list of tariff targets could expand - asked by the BBC if the EU was next, Trump said "it will definitely happen", and suggested it would be “pretty soon”.

The brooding dads made an incredible 7,000-mile journey by boat, plane, and car to London Zoo from their remote island off the southern coast of Chile.
