The Russian military says two of its nuclear-capable strategic bombers have arrived in Venezuela, a deployment that comes amid soaring Russia-U.S. tensions.

Russia's Defense Ministry said a pair Tu-160 bombers landed at Maiquetia airport outside Caracas on Monday following a 10,000-kilometer (6,200-mile) flight. It didn't say if the bombers were carrying any weapons.

The Tu-160 is capable of carrying conventional or nuclear-tipped cruise missiles with a range of 5,500 kilometers (3,410-miles).

Such bombers took part in Russia's campaign in Syria, where they launched the conventionally-armed Kh-101 cruise missiles for the first time in combat.

Russia sent its Tu-160 strategic bombers and a missile cruiser to visit Venezuela in 2008 amid tensions with the U.S. after Russia's brief war with Georgia. A pair of Tu-160s also visited Venezuela in 2013.
