A deal to set up safe zones in Syria will come into force at midnight local time, Russia’s defence ministry says.
The accord on four zones was reached at Thursday’s talks in Kazakhstan between Russia and Iran which back Syrian President Bashar al-Assad.
Turkey, which supports Syrian rebel groups, agreed to act as a guarantor. Moscow says the US, the UN and Saudi Arabia also support the idea.
But some delegates from the rebel forces angrily rejected the plan.

At Friday’s news briefing in Moscow, Russian Deputy Defence Minister Alexander Fomin said attacks by all sides in the “de-escalation” zones should halt from midnight.
The objective is also to “provide the conditions for the safe, voluntary return of refugees” in addition to the speedy provision of relief supplies and medical aid.
The safe zones will remain in place for six months, the Kremlin has said.
Under the plan, the four zones will be established in:
- Rebel-held areas in the north-western province of Idlib and adjoining districts of Latakia, Aleppo and Hama
- Parts of Homs province in the centre, where rebels hold a stretch of territory
- The opposition enclave of Eastern Ghouta, near the capital Damascus
- Daraa and Quneitra provinces, in southern Syria, where rebels have large presence
Mr Fomin said that there had been no bombing raids by Russian aviation in the four zones since 1 May.
But he stressed that Russia’s air force would continue striking so-called Islamic State (IS) elsewhere in Syria.
At Thursday’s talks in Kazakhstan’s capital Astana, Syria’s rebel delegates angrily shouted that they did not accept the deal and walked out.
Reporters at the negotiations said the rebels were unhappy about Iran’s involvement in the deal as a guarantor.
It is unclear whether any of the rebels will abide by the ceasefire.
The US also expressed concern over Iran, saying the country had “only contributed to the violence, not stopped it”.
The Syrian government is not a signatory, but its state news agency has said it supports the plan.
The talks were meant to shore up an oft-violated ceasefire which was originally agreed in December.
A partial cessation of hostilities was declared at the end of last year, but violence has continued on several fronts.
Syria’s war has claimed more than 300,000 lives since it erupted in 2011.
