At least eight people, some of them children, were injured in stabbings in northwest England on Monday, emergency services said. Police said they had detained a man and seized a knife.

Merseyside Police said officers were called at about noon to an address in Southport, near Liverpool. It noted a "major incident" but said there was no wider threat to the public. It asked people to avoid the area. Photos showed several police cars, ambulances and a fire engine behind cordon tape on a residential street.
