Rapper PnB Rock reportedly shot dead at Los Angeles restaurant, here’s what happened

It was one of many shocking moments that played out on television screens across the world as the seat of the world's greatest democracy came under assault from hundreds of protesters angered by Trump's loss to his Democratic opponent Joe Biden in the November presidential election.

One woman was shot and killed in a chaotic crush of people near a stairway. A video posted on social media showed what sounded like a gunshot and an officer in dark clothing armed with a rifle standing near where she fell. Other officers rushed to assist her. The circumstances of her shooting, including who fired the shots, were not clear.

What began as a raucous protest against Trump’s defeat boiled over into a siege of the Capitol, a symbol of U.S. democracy, that paralyzed Congress as it went through the final steps of ratifying the victory of President-elect Joe Biden.

Rioters brawled with police officers, pushed their way past metal security barricades, broke windows and forced their way inside the building, forcing lawmakers in both the House and the Senate to suspend their work and instead go into hiding in offices and other secured rooms. A gray-bearded protester used what looked like a plexiglass riot shield to break a glass window of the Capitol, clearing the way for rioters to climb through.

Members with military experience, including Democratic Representative Jason Crow, a former U.S. Army Ranger, and Republican Representative Markwayne Mullin, a former mixed martial arts fighter, jumped in to help. Representative Reuben Gallego, a former Marine, told fellow House members how to put on their gas masks.

The rioters who stormed the Capitol roamed freely through the corridors, carrying flags – at least one a large Confederate battle ensign – and snapping photographs. One man posed for a photo in the office of House Speaker Nancy Pelosi, the top Democrat in Congress, one booted foot propped on the corner of her desk. Another grinned at a news photographer as he carted a lectern down a hallway. As demonstrators pressed closer to lawmakers, they scuffled with officers. One group discharged a fire extinguisher, leaving a haze. Tear gas blew into the rotunda beneath the iconic building's soaring dome. Some rioters besieged the House of Representatives chamber while lawmakers were inside, banging on its doors, cutting off escape routes.

Security officers piled furniture against the chamber’s door and drew their pistols. Lawmakers and reporters heard loud popping noises from outside and dived for cover on the floor. After 15 minutes, Capitol Police officers secured enough of a pathway through the Capitol to escort House members from the chamber to another location, urging them to hurry as they wound down stairs and through tunnels to avoid the chaos.
