Thousands of people have streamed to the US National Mall in Washington DC as part of country-wide demonstrations to demand greater gun control in America.

The high-profile effort to change the laws follow recent mass shootings in Uvalde, Texas, and Buffalo, New York, that activists say should compel US congress to act.
