Syrian Kurdish-led forces and
Turkey exchanged blame on Saturday for fighting that has rattled a U.S.-brokered cease-fire in northeastern
Syria, as the
Kurds appealed to Vice President
Mike Pence to enforce the deal.
The Syrian
Democratic Forces said in a statement that Turkey has failed to abide by the deal, refusing to lift the siege of Ras al-Ayn, a key border town.
Turkish-backed Syrian fighters encircled Ras al-Ayn just before the cease-fire came into place, trying to crush Kurdish resistance inside.
