London Tube strikes cause chaos

Commuters across the capital are bracing for widespread delays and station closures as the first Tube strike began at midday today.

A second 24-hour walkout is scheduled for Thursday, threatening to paralyze the city's transport system for much of the week.

Transport for London has urged passengers to check their routes and consider alternative travel methods, such as cycling or walking.

The strikes have drawn criticism from business groups and political rivals, who accuse the union of causing unnecessary misery for millions of workers.
