There are more transport problems in the capital because of fog this morning.
TfL suspended ferry services on the Thames because of poor visibility, saying Thames Clipper tickets were being accepted on local buses and Docklands Light Railway.
London City Airport in Docklands also reported delays to flights due to poor visibility.
The fight broke out as the train approached Aldgate East station on Monday night, hours after the Tube strike began.
Fog and train delays added to the misery depriving many travellers of alternative ways to get to work.
