London Explosions - Maybe Three Buses Attacked?

It seems more than one bus might have suffered the explosion. Police were reporting explosions on at least two others buses.

The reported double-decker bus that suffered the explosion was packed with passengers

From the Sydney Morning Herald:

A witness at the Russell Square blast said the entire top deck of that bus was destroyed.

"I was on the bus in front and heard an incredible bang, I turned round and half the double decker bus was in the air,'' said Belinda Seabrook.

She said the bus was packed with people. "It was a massive explosion and there were papers and half a bus flying through the air,'' she said.
