Merkel's office today said they spoke late yesterday, agreeing on the need for Syrian government forces and their Russian and Iranian allies to abide by a UN Security Council resolution for a cease-fire in Syria.
Merkel and Trump called on Russia to stop participating in the bombardment of Damascus' rebel-held suburbs known as eastern Ghouta.
They demanded the government of Syrian President Bashar Assad should be held accountable for the use of chemical weapons, attacks on civilians and the humanitarian blockade.
