Syria's military says it will adhere to a four-day ceasefire to begin on Friday for the Muslim holiday of Eid al-Adha.
The truce will begin at 0600 (0400GMT), reported Syrian TV, adding the army would retaliate against rebel attacks.
The truce was proposed by UN and Arab League envoy Lakhdar Brahimi, who hopes it will lead to a peace process.
The
news came as rebels said they had advanced into several central areas
in Aleppo, Syria's largest city and a key battleground in recent months.
Scepticism
Brahimi
has travelled across the Middle East over the past two weeks to promote
his plan, and on Wednesday won the support of the UN Security Council.
SYRIA CEASEFIRE ATTEMPTS
Arab
League: Observers deployed in late December to oversee compliance with a
peace plan that included an end to violence, the withdrawal of troops
from the streets and the release of political prisoners. But the
monitoring mission was suspended after little more than a month as
fighting continued.
Kofi Annan: Six-point plan for Syria included
the withdrawal of troops and heavy weapons from urban areas, and an
open-ended ceasefire that was meant to take effect on April 12 and lead
to peace talks. But neither side fully adhered to the plan and violence
continued to escalate.
Lakhdar Brahimi: New UN-Arab League envoy
toured the Middle East in October, seeking support for a ceasefire over
the Muslim holiday of Eid al-Adha, which starts on October 26. The
ceasefire, backed by the UN Security Council, is designed to kick-start
political reconciliation.
He also said most opposition groups
would back the truce, though some rebels have expressed scepticism about
the chances of a ceasefire working.
On Thursday, a
statement from the Syrian armed forces carried by state media said:
"Military operations will cease across the entire Syrian territory as of
06:00 (03:00GMT) on October 26 until October 29.
"Syrian
armed forces will, however, reserve the right to reply to terrorists
attacks, attempts of armed groups to reinforce or resupply, or attempts
to infiltrate from neighbouring countries."
Qassem
Saadeddine, a spokesman for the joint command of the Free Syrian Army,
the main armed rebel group, said his fighters would back the truce.
"But we will not allow the regime to reinforce its posts," he told Reuters news agency.
Civil
wars have a trajectory: anger and energy at the beginning, mounting
bloodshed and exhaustion at the end as the losses mount ”
Previous attempts at ceasefires in Syria have collapsed, and the violence has continued to escalate.
The US welcomed the ceasefire, and UN Secretary General Ban Ki-moon said he hoped it would lead to political negotiations.
The uprising against President Bashar al-Assad's government started in March 2011.
Activists say more than 35,000 people have been killed since then, while the UN estimates that at least 20,000 have died.
The
apparent withdrawal of Syrian forces from key Christian and Kurdish
neighbourhoods in Aleppo may be a sign that the government is coming to
accept that it cannot hold the centre of the city. It is not, however, a
fatal blow to its hold on Aleppo. It may even be a tactical retreat,
potentially drawing rebel fighters into a trap. But it may be a
concession that supply lines to its forces in the centre of Aleppo have
increasingly been cut off by the rebels.
That would leave
Syrian President Bashar al-Assad with a dilemma. His government's tactic
in recent months has been to bomb and shell areas held by the rebels -
with military helicopters and fighter jets being used. This firepower
far exceeds what the rebels possess, for now.
But if the
government now uses such force against the areas of Ashrafiyeh and
al-Seryan, it would be a risky strategy as they contain mainly
Christians and Kurds - who have not yet thrown in their lot with the
rebels. The alternative, though, might mean giving up on Aleppo
altogether - a defeat the government would have deemed unthinkable six
months ago.
In Aleppo on Thursday, eyewitnesses and
activists said government forces had moved away from military posts in
the Christian district of al-Seryan and the neighbouring Kurdish area of
Ashrafiyeh.
Rebel fighters had reportedly moved in, although there were also reports of continuing fighting.
"The
centre of the city is right now in the hands of the Free Syrian Army,"
an activist going by the name of Marwan told the BBC World Service.
He said the rebels had placed snipers on rooftops to try to prevent government troops retaking the area.
A
rebel spokesman was quoted as saying opposition fighters had also taken
the south-western neighbourhoods of Salah al-Din and Suleiman a-Halabi.
Meanwhile in Geneva, an expanded team of UN human rights investigators said it had sought a meeting with Assad.
Carla
del Ponte, a former UN prosecutor who led the case against former
Yugoslav leader Slobodan Milosevic and recently joined the Syria
commission, said she saw parallels with her earlier work.
"The similarity of both is that we are handling the same crimes: crimes against humanity and war crimes, for sure," she said.
"My
main task will be to continue the inquiry in the direction of
determining the high-ranking political and military authorities
responsible for these crimes."
