More video of Greek riots, 18 detained, 4 police injured

A communications truck was set on fire in central Athens on Tuesday, and youths hurled rocks and fire bombs at riot police, as a huge demonstration against new austerity measures descended into violence. The demonstration was called by unions, alongside a general strike that has brought the country to a standstill. Firefighters arrived on the scene to extinguish the blazing truck, the second one to be set alight during Tuesday's riots. Tuesday's clashes came at the start of a two-day strike called by unions furious that the new 28 billion euro (40 billion US Dollar) austerity program will slap taxes on minimum wage earners and other struggling Greeks. <br />.RT on Facebook: http://www.facebook.com/RTnews<br />RT on Twitter: http://twitter.com/RT_com
