Boulder authorities will make fresh attempts to ban assault rifles as the Colorado city is just beginning" to grieve after 10 people were killed in the mass shooting at a local supermarket on Monday afternoon.

The mayor of Boulder, Sam Weaver, said on Wednesday morning that the city is likely to appeal against a ruling just 10 days ago by a judge that blocked a ban on the weapons passed by the city in 2018 after a lawsuit that was supported by the National Rifle Association.
