One year of Syrian protests, Japan Earthquake anniversary, Clooney visits Sudan

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. Each week we post a weekly recap of the top news stories of the week, as seen through the lens of both citizen-reported footage and professional news coverage.

• We witnessed devastating scenes from Afghanistan, as 16 civilians were killed and five injured after a US soldier allegedly went on a shooting spree in the south of the country.
• We were saddened to hear of the deaths of 28 Belgians, including 22 children, who were killed in a coach crash inside a Swiss motorway tunnel near Sierre.
• We followed George Clooney as he witnessed the horrific effects from the war crimes that have taken place in Sudan's Nuba Mountains.
• We marked one year since the revolt against Assad's regime began in Syria, even as towns where the uprising began, such as Daraa, continued to be mercilessly bombed.
• We observed a 'mini-Tuesday' for GOP candidates on the US campaign trail, as Rick Santorum pulled off a southern sweep with wins in Alabama and Mississippi.
• We viewed solemn reflections in Japan one year after the most powerful earthquake in their history struck, causing a devastating tsunami and the now infamous Fukushima nuclear plant incident.
• We saw heightened violence between Israelis and Palestinians leave at least 20 people dead.
• We were awestruck as a massive tornado hit Dexter, Michigan on Thursday, leaving several homes destroyed as it swept through the town.
• We watched David Cameron receive a warm White House welcome from President Obama as the UK and the US celebrated their 'special' relationship.
