Announcement comes after Russian leader held a lengthy phone call with US President Donald Trump.

Russian President Vladimir Putin has agreed to halt attacks on energy infrastructure targets in Ukraine for 30 days after a phone call with US President Donald Trump.

Putin ordered the Russian military to stop strikes against energy facilities, the Kremlin said in a statement following a lengthy phone call between the two leaders on Tuesday. But he stopped short of accepting a broader US-backed 30-day ceasefire proposal that Ukraine has said it is ready to implement.
