Police in the US city of Chicago have asked for more help to combat gun violence after more than 60 people were shot over the weekend. At least 10 people were killed in the city and police say most of the shootings were gang related.

“We will not be defeated,” police chief Fred Waller told reporters on Sunday. “We need more help from our judicial system. We need more help from our federal partners, and we are getting it,” he added.

Most of the shootings happened on Sunday with 30 people shot between midnight and 03:00. The majority of the incidents reportedly occurred in Chicago’s south and west sides.
