Trains are at a standstill across most of the London Underground network as Tube workers stage another walkout.

The industrial action, which follows a 24-hour walkout by Underground staff earlier this month, is part of a dispute around pensions and jobs.

It coincides with the first of three days of planned strikes this week by national rail workers across the country in a separate dispute.

Transport for London (TfL) has "strongly encouraged" people to avoid travelling today - Tuesday, June 21 - if possible.

Most services are suspended, but a reduced timetable is operating on sections of some Underground lines this morning.
