Russia could attack a Nato country within the next five years, the Western military alliance's chief has said in a stark new warning.
"Russia is already escalating its covert campaign against our societies," Mark Rutte said in a speech in Germany. "We must be prepared for the scale of war our grandparents or great-grandparents endured."
He echoed similar statements about Russia's intentions made by Western intelligence agencies, which Moscow dismisses as hysteria.
Rutte's warning comes as US President Donald Trump tries to bring an end to Russia's full-scale invasion of Ukraine, launched in February 2022.
Earlier this month, Russia's President Vladimir Putin said his country was not planning to go to war with Europe, but it was ready "right now" if Europe wanted to - or started a war.
