In pictures: Uber cab protests in London and the rest of Europe
European cities have come to a standstill as cab drivers protest against the rise of taxi apps such as Uber.
Uber customers can hail a ride using their smartphone, which will show them the nearest vehicle available, rather than having to flag a cab.
London, Barcelona, Madrid, Rome, Paris and Berlin have suffered traffic disruption due to the demonstration.
Here's how the protest is looking on London's traffic cameras.
