Major world powers have agreed to a "cessation of hostilities" and to the delivery of immediate aid in Syria, U.S. Secretary of State John Kerry announced early Friday.
He spoke in Munich, Germany, where top diplomats from more than a dozen countries, including the United States and Russia.
"I'm pleased to say that as a result today in Munich, we believe we have made progress on both the humanitarian front and the cessation of hostilities front, and these two fronts, this progress, has the potential -- fully implemented, fully followed through on -- to be able to change the daily lives of the Syrian people," Kerry said.
"First, we have agreed to accelerate and expand the delivery of humanitarian aid beginning immediately," he told reporters. "Second, we have agreed to implement a nationwide cessation of hostilities to begin in a target of one week's time. That's ambitious, but everybody is determined to move as rapidly as possible to try to achieve this."
Turkish Foreign Minister Mevlut Cavusoglu said Friday via Twitter that "stopping the airstrikes" was what was important. The agreement to cease hostilities is an "important step," Cavusoglu said. "What is important now is embracing this opportunity, stopping the airstrikes, ceasing targeting civilians and providing humanitarian access."
On Thursday, Russian Foreign Minister Sergey Lavrov in Munich said Russia would continue its airstrikes on ISIS, Jebhat al-Nusra and other affiliated terrorist groups, as they are not subject to the truce, while at the at the meeting of the 17-nation International Syria Support Group.
At least 35,000 to 40,000 refugees have come into camps on the Syrian side of the Turkey-Syria border in the latest flood of people fleeing Russian bombardment, Turkish Deputy Prime Minister Yalcin Akdogan said Friday at a news conference in the Turkish border town of Kilis.
Turkey will continue its open door policy, but "not because someone told us to," Akdogan said. "No one has the right to give us a lesson in humanity," he said, because "Turkey has been left alone to struggle on its own."
More than 2.6 million refugees are living in 26 camps inside Turkey, he told reporters at the news conference Friday.
Any potential ceasefire would not apply to terrorist organizations operating in Syria. And Kerry stressed that the longer the conflict persists there, the more extremists have to gain.
He also said that the real test of talks will be whether all the parties involved honor their commitments and implement them. Ending the five-year civil war will require a plan for a political transition, he said.
The Syrian uprising began in March 2011. At least 250,000 people have died and 12 million have been displaced because of the conflict, according to the United Nations.
"What we have here are words on paper. What we need to see in the next few days are actions on the ground," Kerry told reporters.
His point was echoed by Lavrov, the Russian foreign minister, who spoke at the same news conference in Munich.
Lavrov said that a ceasefire would be difficult but characterized what was announced Friday as a "step forward." "We have a common determination to reduce the suffering of the Syrian people," he said.
