Germany faces new calls to send modern tanks to UkraineOSLO/BERLIN, Jan 5 (Reuters) - France's decision to send light AMX-10 RC armoured combat vehicles to Ukraine prompted renewed calls from within German Chancellor Olaf Scholz's coalition for Berlin to send more modern fighting vehicles to help Kyiv in the war against Russia.Ukrainian President Volodymyr Zelenskiy on Wednesday urged Western allies to provide his army with tanks and heavy weapons to combat the Russian forces.He thanked France for the AMX-10 RC vehicles, saying other allies should take that as a signal and that "there is no rational reason why Ukraine has not yet been supplied with Western tanks".Scholz has ramped up defence spending and sent aid and weapons to Ukraine since Russia invaded last February, but has, like other Western powers, sometimes hesitated before sending powerful weapons for fear of risking direct conflict with Moscow.He also made it clear that he did not want to go it alone on sending heavy weapons to Ukraine and that he would coordinate deliveries with other members of the NATO alliance."
