Moscow Metro bombing masterminds 'will be destroyed'

The masterminds behind a double suicide bombing on the Moscow Metro will be destroyed, Russia's leaders have said.

The attacks, in the morning rush hour, killed at least 38 people and injured more than 60, officials say.

No group has said it carried out the attacks, but security services have blamed rebels from the North Caucasus - which includes Chechnya and Ingushetia.
