This Week's Top News Stories on YouTube--An economic and political Greek roller coaster, Occupy protests heat up, and an incredible emergency airliner

Everyday on the CitizenTube Channel (and @CitizenTube on Twitter), along with our curation partners @storyful, we look at how the top news stories are covered on YouTube. Every week we'll post a weekly recap of the top news stories of the week:

• We tracked a roller coaster week for Greece as the country went back and forth on whether to hold a referendum on an EU bailout for the country that stole headlines at the G20 meetup in Cannes, France.
• We watched intense Occupy protests in Denver and once again in Oakland as police in both cities used non-lethal weapons to reign in demonstrators.
• We witnessed an amazing emergency landing of a Boeing 767 airliner with no landing gear and 231 passengers on board that touched down in Warsaw, Poland after taking off from Newark, New Jersey.
• We noted the loss of thirteen American military personnel and three Australian soldiers in separate attacks by the Taliban in Afghanistan.
• We followed Herman Cain on the US campaign trail as he defended himself against accusations of sexual harassment while he was president of the National Restaurant Association in the 1990s.
• We observed roads turning into rivers in Bangkok, Thailand as floodwater in the city and surrounding areas steadily inundated neighborhoods in the country's worst flooding in decades.
• We were amazed by the powerful, early season snowstorm in the US Northeast that was blamed for at least 29 deaths and enormous power outages.
• We monitored the quick breakdown of a supposed Arab League deal with Syria for the country's security forces to stop the violent suppression of anti-government demonstrations which lead to over a dozen people killed.
• And finally, we celebrated Halloween along with YouTubers around the world and saw US politicians get into the spirit too!
