Explosions in UK Public Transit System

Several people have been injured as explosions today rocked the London Underground subway network, prompting its closure. Travelers emerged from tunnels covered in blood and soot. A blast also hit at least one bus, witnesses said. Scotland Yard declared the emergency a "major incident." The cause of the blasts was not immediately known.

I am doing fine and am not in London today.  Our thoughts are with our friends in the UK.
