UPDATED: Storify: Europe's general strike, in pictures

Protesters march in Lisbon during a general strike on November 14, 2012. General strikes in Spain, Portugal and Italy took place on the day of action called by European unions and joined by activists as anger over governments' tight-fisted policies boils over.

We'll be keeping an eye on the situation as it unfolds. For now, Spain and Italy appear violent, while Athens is mostly peaceful. Flights and trains have been delayed or out-right cancelled because of strikes and protests in Spain.
