British police on Sunday declared a “major incident” after several people were stabbed in the centre of the country’s second city, Birmingham.
Violence broke out at about 12:30 am (2330 GMT Saturday) in and around the Arcadian Centre, a popular venue filled with restaurants, nightclubs and bars.
West Midlands Police confirmed “a number” of stabbings but said it had no information on reports that shots had been fired. No further details on casualties were immediately available.
The incident comes after several previous mass casualty stabbings, including one in the Scottish city of Glasgow on June 26, in which six people were injured, including a police officer.
A man was charged with murder after three people were killed in a park in Reading, west of London, the previous week in an attack investigated by counter-terrorism police.
