BEIRUT – The United States and Russia on Monday announced plans for a landmark “cessation of hostilities” to take effect in war-torn Syria on Feb. 27, excluding the main jihadi factions.
The announcement drew a conditional acceptance from the main opposition grouping and came just one day after the deadliest jihadi attack in the nearly five-year war, with 134 people — mostly civilians — killed in a series of blasts near Damascus.
In a joint statement, Washington and Moscow said the partial truce would begin at midnight Damascus time (2200 GMT Friday) and apply to parties to the conflict that have committed to the deal — but not to the Islamic State group or Nusra Front, an al-Qaida affiliate.
Parties wishing to be included in the agreement have until noon Damascus time on Friday to inform Moscow or Washington of their intention to honour the cease-fire.
“If implemented and adhered to, this cessation will not only lead to a decline in violence, but also continue to expand the delivery of urgently needed humanitarian supplies to besieged areas and support a political transition to a government that is responsive to the desires of the Syrian people,” U.S. Secretary of State John Kerry said.
U.S. President Barack Obama and Russia’s President Vladimir Putin discussed the deal in a phone call, the White House said.
“This is a moment of opportunity and we are hopeful that all the parties will capitalize on it,” White House press secretary Josh Earnest said.
U.N. Secretary-General Ban Ki-moon called the cease-fire a “long-awaited signal of hope” and urged all sides to abide by it.
Putin said Moscow will do “whatever is necessary” to ensure that Damascus respects the agreement.
“We are counting on the United States to do the same with its allies and the groups that it supports,” he said in a televised address.
There was no immediate reaction from Damascus, but the main grouping of opposition factions said it “agreed to respond positively to international efforts to reach a truce deal.
President Bashar Assad issued a decree for parliamentary elections on April 13 shortly after the truce was announced.
The opposition High Negotiations Committee said its “commitment to the truce is conditional” on the lifting of sieges, release of prisoners, a halt to bombardment of civilians and the delivery of humanitarian aid.
On Monday, state news agency SANA reported a convoy of 44 trucks carrying humanitarian aid had entered Moadamiyet al-Sham, near Damascus, overseen by the Red Crescent and the United Nations.
Once the cessation of hostilities takes hold, the United Nations will work to secure “access to as many places as possible in order to deliver humanitarian aid,” U.N. spokesman Stephane Dujarric said earlier.
The 17-nation group backing Syria’s peace process agreed at a meeting in Munich to implement a cease-fire within a week, but the truce never materialized.
Ban said the truce announced Monday “contributes to creating an environment conducive for the resumption of political negotiations,” which had been scheduled to resume this week.
A halt in hostilities in Syria would come after five years of brutal civil war that have killed more than 260,000 people and seen half the population displaced, including over 4 million overseas.
In return, the groups would be assured of protection from Russian and U.S.-led coalition planes.
The two powers are pursuing separate air wars in Syria, with Russia pounding rebel targets and the coalition focused on Islamic State.
Islamic State on Sunday claimed responsibility for two deadly attacks in regime-held areas, which a monitor said killed 134 people near the Sayyida Zeinab shrine south of Damascus and at least 64 in the Al-Zahraa district of Homs.
The bombings near the shrine marked the deadliest jihadi attack since Syria’s conflict erupted in March 2011, said the Syrian Observatory for Human Rights, a Britain-based monitoring group.
Russia began airstrikes in Syria last September against what it said were “terrorists” but has been accused of bombing nonjihadi rebel forces in support of Assad, a longtime ally.
Iran has sent military advisers to Syria and the Tehran-backed Lebanese Shiite movement Hezbollah has deployed at least 6,000 militants to fight alongside Assad’s forces.
Tehran would have to be on board for any cease-fire to work, and Russian Defense Minister Sergei Shoigu made a surprise visit to Tehran on Sunday, saying he was delivering a “special message” from Putin to President Hassan Rouhani.
The rise of Islamic State, which has seized large parts of Syria and neighboring Iraq and become the pre-eminent global jihadi group, has focused attention on the need for a solution.
The group has used its ultra-radical view of Islam to justify kidnapping minorities, including Assyrian Christians in northeast Syria.
On Monday, Islamic State released 42 Assyrians, the last remaining hostages from a wide-scale kidnapping in the northeast province of Hassakeh nearly one year ago, the Assyrian Monitor for Human Rights said.
But Islamic State also advanced against government forces in northern Aleppo province, cutting the only supply route linking the west of Aleppo with other government-held territory, the Observatory said.
Fierce clashes were raging in the area, and if government forces are unable to recapture the road, it could slow their offensive.
