The US "strongly condemned" the reported vandalism and attempted arson at the Indian consulate in San Francisco on Sunday (local time).
According to Diya TV, Khalistanis set fire to the Indian consulate between 1:30 and 2:30 a.m. However, it was promptly extinguished by the San Francisco Fire Department.
According to the report, while the damage was minor, no staff members were wounded in the incident. Khalistan supporters allegedly released a video in response to the tragedy.
"The United States strongly condemns Saturday's reported vandalism and attempted arson against the Indian Consulate in San Francisco." Vandalism or violence against diplomatic facilities or foreign diplomats in the United States is a criminal offence," US State Department spokesperson Matthew Miller tweeted.
The event occurred months after a group of pro-Khalistani demonstrators assaulted and destroyed the Indian consulate in San Francisco in March, provoking outrage from the Indian government and India-Americans, who urged quick action against those guilty.
Protesters shouting pro-Khalistan slogans tore down improvised security barriers erected by local police and placed two so-called Khalistani flags within the Consulate grounds. These flags were quickly removed by two consular employees.
The attack on the Indian consulate occurred just hours after pro-Khalistani activists tore down the Indian tricolour that flew above the Indian high commission in London.
India has asked Canada to intervene immediately against so-called Khalistan extremists who plan to march to Indian embassies in Toronto and Vancouver after falsely blaming Indian diplomats and security agencies for the death of designated terrorist Hardeep Singh Nijjar. On June 19, the 45-year-old Khalistan Tiger Force (KTF) head was assassinated in an inter-gang conflict in Vancouver's Sikh-dominated Surrey district. Nijjar had ties to the outlawed organisation SFJ, which is led by a recognised terrorist based in the United States.
