[Q]: Moscow (CNN) -- Russia's upper house of parliament voted Wednesday to revoke the right of President Vladimir Putin to use troops in Ukraine as efforts continue to calm a separatist uprising in Ukraine's east. The Federation Council had approved Putin's request for a resolution allowing the use of force on March 1. But Tuesday, Putin sent a letter to the speaker of the upper house seeking to cancel the resolution. One lawmaker voted against revoking the powers Wednesday, with 153 in favor. Putin's request was made in light of ongoing talks on how to settle the crisis in Ukraine's eastern regions, said presidential spokesman Dmitry Peskov.NATO agrees to a package of support to help Ukraine defend itselfRussia's Federation Council cancels resolution authorizing use of troops in UkrainePresident Vladimir Putin asked for the step in light of peace talks, his spokesman saysJohn Kerry and other NATO foreign ministers are meeting in Belgium

[Q]: (CNN) -- A Texas group run by a self-described anarchist has posted what appears to be the first video of the live firing of a handgun created with a 3-D printer. The 53-second video shows a single shot being fired from The Liberator, a plastic handgun that, with the exception of its metal firing pin, was assembled from parts made with a 3-D printer, according to Defense Distributed. The gun appears unscathed after the test firing, although the brief clip does not reveal anything about its range or accuracy. The nonprofit group, founded by 25-year-old law student Cody Wilson, has posted instructions for the gun online so other people can duplicate it. The gun was created with a Stratasys Dimension SST printer, which can be purchased online for as little as $8,000.Group showcases test firing of a gun made with a 3-D printerSelf-styled anarchist created "The Liberator," from plastic, with a nail for a firing pinBlueprints for the gun have been posted online so others can duplicate itDemo comes as lawmakers are calling for bans on printed handguns
