Two suicide bombings hit the Moscow metro on Monday morning, killing at least 39 people and injuring dozens more. The rush-hour blasts took place about 40 minutes apart at the Lubyanka and Park Kultury stations.

"I was shocked when I learned about the tragedy. I will race at the upcoming grand prix in Malaysia with a black armband in memory of the people who died or were injured at Lubyanka and Park Kultury," Petrov said.

Petrov, 25, signed in January a yearlong contract with an option for an extra two years with Renault.

The Russian racer had to retire from his first two Formula One races, due to technical problems in Bahrain and after skidding of the track in Australia.

The Malaysian Grand Prix will be held on April 4 at the Sepang International Circuit, about 60 kilometers south of the capital city Kuala Lumpur.
