An Air France plane is seen on the tarmac at Nice International airport in NiceAir France says a plane carrying 495 passengers and 22 crew was diverted on its way from Shanghai to Paris after Russia announced at short notice that part of its airspace was closed for a military exercise. The company said flight AF111 was forced to land in Hamburg, Germany, early Wednesday to refuel because the plane had too little fuel on board to complete the flight following its detour. Hamburg Airport confirmed that the plane landed shortly after 6 a.m. (0500 GMT) and was able to take off for Paris again after an hour and a half.  It wasn’t immediately clear if Russia’s military exercise was linked to the increased troop activity on its western border with Ukraine. Meanwhile, the World Bank warned Wednesday that Russia’s economy could contract this year if the country is hit with more serious sanctions following its annexation of Crimea. The organization said in its annual report that it expects the Russian economy to grow 1.1 percent this year if the fall-out from the Crimean crisis is short-lived, but warned of a 1.8 percent fall if Russia is hit with more serious sanctions than those already specified.
