MOSCOW, Jumada I 25, 1437, Mar 5, 2016, SPA -- Russian Foreign Minister Sergei Lavrov and U.S. Secretary of State John Kerry, in a late phone conversation on Friday called for a prompt start to the next round of Syria peace talks, Reuters cited Russia's Foreign Ministry as saying in a statement. The talks, under the aegis of the United Nations were originally due to begin on March 7 in Geneva, but have been postponed until March 9, due to " logistical and technical reasons and also for the ceasefire to better settle down," the U.N. said. The ministry said in a statement that the two sides called to start the negotiations as soon as possible between the Syrian regime and the whole spectrum of the opposition. Kerry and Lavrov also reaffirmed the need for mutual cooperation to ensure the end of hostilities in Syria, the ministry said. --SPA 11:41 LOCAL TIME 08:41 GMT www.spa.gov.sa/w
