The heads of Nato and the European Commission have warned that Russia is growing increasingly reckless and vowed to respond to a "new normal".

"Leipzig marks a new escalation on European Union soil directly attributed to Russia," said Commission President Ursula von der Leyen, a day after Germany blamed Russia for a failed drone attack last month on Leipzig airport, BBC reported. 

"We have to step up and that means being ready to respond to Russia's recklessness faster and better," von der Leyen said. Nato Secretary General Mark Rutte said the whole alliance, which includes the US, stood "in full solidarity with Germany".
