Asia-Pacific stocks from Shanghai to Tokyo and Sydney to Hong Kong plunged on Monday by levels not seen in decades, as global markets continue to reel from US President Donald Trump's tariffs.

The Shanghai Composite was down more than 8% at one point, Hong Kong's Hang Seng dropped more than 13% and Japan's Nikkei 225 closed down by 7.8% - moves that one analyst described to the BBC as a "bloodbath".

European markets too fell in early trading, with banks and defence firms seeing the biggest drops. This follows global slumps last week after Trump announced new tariffs between 10% and 46% on most countries.
