US Capitol on high alert as pro-Trump demonstrators converge for rally

The US Capitol is on high alert ahead of a rally in support of the pro-Trump protesters who ransacked the building on January 6.

Hundreds of police officers will be on duty around the US Capitol on Saturday braced for a rally by supporters of the hundreds of people who breached the building on January 6 trying to overturn former President Donald Trump's election defeat.

A black eight-foot-high (2.44 m) fence which surrounded the white-domed building for about six months after the attack is back, 100 National Guard troops are on standby and security officials are performing additional checks on travellers arriving at Washington's nearest airport in an effort to prevent violence.
