Assuaring the security of Indian diplomats US National Security Advisor Jake Sullivan has condemned the attack on the Indian Consulate in San Francisco by Khalistani separatists on Sunday.

He acknowledged that the US State Department is in contact with local law enforcement.

"We condemn the attacks on the Indian Consulate in San Francisco. We are dedicated to the safety and security of these facilities as well as the diplomats who work there" Sullivan says.

Even after the "condemnation," more than 200 demonstrators flying Khalistan flags descended on the Indian Consulate in San Francisco on Wednesday for a planned demonstration, despite the San Francisco Police Department's (SFPD) increased security presence.

Unlike on Sunday, when the Consulate was attacked, the demonstrators were heavily walled across the road, with uniformed SFPD police standing watch and patrolling the area.

Pro-Khalistan slogans were chanted by the protesters.

The organizers used microphones to deliver anti-India statements in both English and Punjabi, as well as to criticize the Punjab Police for alleged human rights violations.

Meanwhile, White House National Security Council spokesperson John Kirby has said that vandalism at the Indian Consulate in San Francisco is "absolutely unacceptable" and that the US condemns it.

Following the vandalism in London, supporters of Khalistan assaulted the Indian Consulate in San Francisco. Social media users shared videos of fans smashing down the doors and barging into the office.

Images circulated online show a large mob wielding Khalistan flags placed on wooden poles and smashing glass doors and windows of the consulate building. They chanted pro-Khalistan chants as they burst through the city police's temporary security barriers and placed two Khalistani flags inside the grounds.
