Tube strike disrupting millions of passengers
Thousands of Tube passengers have endured delays because of strike action over planned job cuts and ticket office closures.
The first of two planned 48-hour strikes by the RMT and TSSA unions means there is a limited tube service until Friday morning.
Unions have said they will take part in talks on Friday aimed at resolving the dispute.
But London Underground (LU) urged them to meet earlier and suspend the strike.
