At least four people were killed in the explosion

At least three Russian soldiers have been killed and other people injured in a blast in Chechnya's capital, Grozny.
Local officials said it was a suicide bombing, launched when soldiers left their vehicle.
Differing reports said three or four soldiers were killed, and that there were either one or two suicide attackers.
Earlier, Russian officials said the blast was an accident during a mine-clearing operation.
Russia fought two wars in Chechnya more than a decade ago.
The unrest has since spread to the neighbouring Russian republics of Dagestan and Ingushetia.
