Covid-19 restrictions rallied in cities across Europe on Saturday as several nations reimposed partial lockdowns to fight new surges in infections.The coronavirus, which has killed more than 2.7 million people, has been spreading faster recently, with the number of new infections up globally by 14 percent in the last week, according to AFP data.That has forced governments to impose social distancing and movement restrictions again, even as vaccines are rolled out, with residents in Poland, parts of France, and Ukraine's capital the latest to face fresh curbs.But populations have grown increasingly weary of the economically painful restrictions, and frustrations spilled over in cities across Europe with thousands marching in Germany, Britain.
