A picture is worth a thousand words-even on a cell phone.

At least 33 people were killed Thursday in three explosions in London's subway system, a senior police official said. Deputy Assistant Commissioner Brian Paddick said others died in an explosion on a bus in central London but gave no figures. The second blast, at 8:56 a.m. (0756GMT), in the King's Cross area of north London, killed 21, Paddick said. (AP Photo / Alexander Chadwick)
