This comes less than a week after a gunman killed three people in what police described as a random attack was being hunted in the western US state of Washington and at least 10 people were killed and several injured in a mass shooting in a predominantly Asian city in southern California.

A group of US senators reintroduced on Monday a federal Assault Weapons Ban and legislation that would raise the minimum purchase age for assault weapons to 21.

The US legislation allows keeping weapons without registration or license in 43 states, which causes frequent fatal shooting incidents.

There have already been about 40 mass shootings in the US since the beginning of the year, according to Gun Violence Archive analysts.
