All Indians were safe in the deadly Paris terror attacks, External Affairs Minister Sushma Swaraj said on Saturday.

"I have spoken to Indian Ambassador in France. He has informed me that all Indians are safe. France has advised citizens to stay indoors," she tweeted.

Deputy Chief of Mission Manish Prabhat earlier told TimesNow television channel: "As of now, there is no report of any Indian being killed."

He said that since the embassy staff was not allowed to go out due to restrictions imposed by French authorities, "we don't have a ground report and there is no independent way of finding it out".

Prabhat said Paris was home to some 100,000 Indians.

Earlier, Indian Ambassador Mohan Kumar tweeted: "We hope all Indians are safe. Our prayers (are) with families affected and solidarity with France."

After the horrific serial attacks, the Indian embassy in France opened its helpline number.

"Indian Embassy telephone 0140507070 open, we hope all Indians are safe. Our prayers with families affected and solidarity with France," Kumar said.
