Russian President Putin expressed reservations about a proposed 30-day ceasefire in Ukraine, acknowledging it as a good initiative but emphasizing the need for further discussions on details before reaching an agreement.

The US-proposed ceasefire deal was first accepted by Ukraine on March 11, after it expressed willingness to accept the same post the US-Ukraine peace talks in Jeddah, Saudi Arabia.

Russia's Vladimir Putin said he agrees in principle with a U.S. proposal for a 30-day ceasefire in Ukraine, but that the terms need to be worked out.
