The US State Department has condemned the vandalisation of the   Indian consulate in San Francisco   by suspected Khalistan separatists.

US State Department spokesperson Matthew Miller tweeted: "The U.S. strongly condemns the reported vandalism and attempted arson against the Indian Consulate in San Francisco on Saturday. Vandalism or violence against diplomatic facilities or foreign diplomats in the U.S. is a criminal offense."

As per local US channel named Diya TV, the consulate was set on fire  on Sunday morning.

" The fire was suppressed quickly by the San Francisco Department, damage was limited and no staffers were harmed," the news channel tweeted.

Meanwhile, the Indian government has served demarche to Canada on the suspected planned protests by pro-Khalistan terrorist outfits outside the Indian High Commission in Ottawa, and two consulates in Toronto and Vancouver on July 8, media reports said.

It has asked the Justin Trudeau government to take strong measures to prevent the protestors from gathering close to missions and consulates, desecrating the Indian National Flag, sticking pamphlets or items to the boundary fence and throwing projectiles into the Indian diplomatic premises in Canada, reports Hindustan Times.

While the Canadian High Commissioner was called to the South Block on Monday to convey Indian concerns very bluntly, the note verbal was sent to Global Affairs Canada early morning Tuesday (IST), the Indian newspaper reported.

Canadian Foreign Minister Melanie Joly, meanwhile, said the country takes the safety of diplomats very seriously.
