(FOX) — The Russian government has been mum on how long two nuclear-capable strategic bombers will stay in Venezuela as Secretary of State Mike Pompeo decried the collaboration between “two corrupt governments.”

Russia’s Defense Ministry on Monday announced that a pair of Tu-160 bombers landed at an airport outside Caracas. The ministry didn’t reveal whether the bombers — which flew over 6,000 miles to reach the socialist country — carried any weapons. An An-124 heavy military transport plane and an Il-62 long-haul plane also arrived in Venezuela.
