At least six people were killed in the shooting that occurred in a Wisconsin Gurdwara yesterday when members of the community were preparing for the Sunday morning prayers.
The US mission in a statement this morning expressed sympathy and extended condolences to the Sikh community in the United States and India, saying its members were "deeply saddened by the senseless loss of lives and injuries".
"Our hearts, thoughts, and prayers go out to victims and their families. An investigation into the incident has begun. Any incident like this one is tragic, especially when it happens in a place of worship," it said.
Earlier, US President Barack Obama expressed his grief and condolences at the incident.
The embassy said the Sikh community in the US meaningfully enhances the American social fabric.
"The United States takes very seriously the responsibility to respect and protect people of all faiths. Religious freedom and religious tolerance are fundamental pillars of US society," it said.
