At the time of writing it looks like four bombs have gone off in London, three on the tube and one on a bus. The tube is going to be closed all day and there are no buses in central london (zone 1). Mainline railway stations are mostly open with trains running but many trains have been terminated before reaching London. Trains that would normally terminate in paddington are terminating in Reading.

Casualties are estimated at 150 and deaths much lower but information is still a little scarce and sometimes conflicting. The hospitals seem to be coping well as are the emergency services.

My wife works near marble arch and is still wondering if she is going to get home tonight, luckily her brother has a flat in london where she could stay. A lot of companies are offering to put employees up in hotels if they can't get home tonight.
