Fighting between Syrian rebel and government forces eased on Saturday as a Russian-led effort to shore up a ceasefire took effect, although battles continued on important frontlines near Hama and Damascus, rebels and a war monitor said. The deal to create “de-escalation” zones in the major areas of conflict in western Syria took effect at midnight. The initiative was proposed by Russia, President Bashar al-Assad’s most powerful ally, with the support of Turkey, which backs the opposition. Iran, Assad’s other major ally, also backed it.
