🚨🚨 Breaking news 🚨🚨
Stock markets around the world fell following the introduction of tariffs by President Donald Trump on goods entering the US from China, Canada and Mexico.
Trump has imposed 25% tariffs on imports from Canada and Mexico, and 20% tariffs against China.
Canada and China announced their own import taxes on US goods, while Mexico said it had "contingency plans", sparking fears of full-blown trade war.
The three major stock market indexes in the US sank following the news, while the FTSE 100 index of the UK's biggest publicly-listed companies opened lower on Tuesday and stock markets in Asia were also down.
