BEIRUT (AP) — The Russian Defense Ministry said a 48-hour cessation of hostilities has been declared in the divided northern Syrian city of Aleppo and activists reported a relative calm in Syria's largest city on Thursday.
In past months, Aleppo has witnessed fierce fighting and bombardment, which has claimed the lives of hundreds of people on both sides of the contested city.
Russia said the truce went into effect after midnight Wednesday. Several similar truces have been declared in the city in recent months.
The Britain-based Syrian Observatory for Human Rights said the city was calm early Thursday but that government warplanes later bombarded several rebel-held neighborhoods in Aleppo.
The Observatory said that since the latest round of violence began on April 22, 627 people have been killed and some 2,900 wounded. It said the dead included 124 minors under the age of 18.
Rebels seized part of Aleppo from forces loyal to President Bashar Assad in 2012. Assad's forces, backed by Russian airstrikes, have nearly encircled rebel-held parts of the city in recent months.
Aleppo-based activist Baraa al-Halaby said opposition fighters in the city — once Syria's commercial center — were not informed about the truce. He said that although there is a truce, government forces as well as Russian and Syrian warplanes have been targeting the Castello road that links rebel-held areas with the rest of the country, preventing people from leaving.
"This is a joke," al-Halaby said by telephone, speaking of the alleged cease-fire. "The Castello road has been bombarded with barrel bombs for the past 12 hours."
Jan Egeland, who is leading the U.N. Syria envoy's effort to get humanitarian aid into the country, called the truce a "confidence-building measure" and a key step toward possibly getting convoys into Aleppo "where it has been impossible to do humanitarian work in many areas for too long."
"The fighting has gotten worse. The bombing is worse. The protection needs of the civilian population are being trampled upon across the Syrian map," he told reporters in Geneva, referring to the overall security situation in Syria.
"It is then very positive that a truce for 48 hours was declared today in Aleppo — Aleppo city — we need more of this and we need it in Aleppo and we need it elsewhere because we are acutely aware that the access we have now can end tomorrow," Egeland added.
Humanitarian aid organization Mercy Corps said there has been "a significant decrease in violence, although there have been minor infringements" since the cease-fire went into effect.
"Mercy Corps is deeply appreciative of any opportunity to deliver life-saving aid safely and for the people of Syria to have relief from the seemingly endless violence of this conflict," said Xavier Tissier, North Syria director for Mercy Corps.
"However, a scant 48 hours is not enough time to ensure that the hundreds of thousands of vulnerable people in east Aleppo have the food and other essentials they need," he said. "Incredibly short, one-off windows cannot be considered a serious attempt at permitting humanitarian access. We need permanent, sustained, unfettered access that the people of Aleppo can depend on."
Near Aleppo, fighting continued between members of the Islamic State group and the U.S.-backed predominantly Kurdish Syria Democratic Forces near the IS stronghold of Manbij.
The U.S. Central Command said that as of Monday, the Syrian Arab Coalition, which is part of the SDF, completed the first phase of their operation to free the town of Manbij by securing the territory surrounding the IS-held town.
"After clearing Daesh from this area they are now ready for the second phase to liberate the city itself," the CENTCOM statement said, using an Arabic acronym to refer to IS. It added that since the operation against IS in Manbij began in late May, the U.S.-led coalition has conducted more than 190 airstrikes in the vicinity of Manbij.
