WASHINGTON (AP) — Secretary of State John Kerry says both sides may have violated Syria's ceasefire.
But he says no breaches have been significant enough to shatter the three-day-old "cessation of hostilities."
Speaking alongside German Foreign Minister Frank-Walter Steinmeier, Kerry says a U.S.-Russian-led task force is investigating all claims of violations.
And he says the goal should be making the truce stick, not finding ways to undermine it.
Kerry says he spoke by telephone with Russian Foreign Minister Sergey Lavrov and the two are committed to dealing with reported transgressions.
Kerry welcomed the news that aid has reached thousands of Syrians.
Still, he criticized Syrian troops and officials for blocking some deliveries and stealing from others.
He says the government should "try to show some measure of decency, if that is even possible."
