BRUSSELS (Reuters) - Thousands of Belgian students skipped classes for the fourth week in a row on Thursday to protest against global warming, part of a growing youth protest around the world.

Beating drums, chanting and carrying signs, some 30,000 teenagers braved the cold in Brussels and other cities to call on local politicians for stronger action to prevent climate change.
