Syrian state media said the brief "humanitarian pause" came into force Thursday shortly after a Berlin meeting at which President Vladimir Putin faced German and French criticism over Russian and Syrian air raids on Syria's second city.

"We guarantee a safe exit, save your families," blared a Syrian army message near one of two exit corridors - near Aleppo's Castello road and its Bustan al Qasr quarter - designated by the regime of Syrian President Bashar al-Assad.

State television showed green buses waiting along the designated exit routes.

'Clashes,' not departures

There had been no reports of people trying to leave, said Rami Abdel Rahman, who heads the Britain-based Syrian Observatory for Human Rights.

Two hours into the "pause" the French news agency AFP reported that shots had been fired amid "clashes."

"Without UN supervision no one will leave," Ibrahim al Hajj of Syria's civilian White Helmet rescue team told the German news agency DPA, referring to up to 300,000 people trapped for months in eastern Aleppo.

North of Aleppo, Turkish airstrikes had targeted a Syrian Kurdish village late Wednesday night, added the Turkish news agency Dogan.

On Wednesday, Syria's foreign ministry had said troops would pull back to facilitate the exit of rebel fighters, who had also said they would not leave eastern Aleppo, the last major urban center controlled by opposition forces in Syria.

'War crime,' says France's Hollande

Putin, visiting Berlin on Wednesday evening, was told by French President Francois Hollande that joint Syrian and Russian bombing of Aleppo was a "war crime."

Host German Chancellor Angela Merkel described events in Aleppo as "inhumane and cruel" and said the three-way talks with Putin were "very tough."

Ahead of the Berlin encounter, Moscow said the "pause" would be extended from eight to 11 hours.

Syrian and Russian warplanes would skirt Aleppo by 10 kilometers (six miles), said Russian military spokesman Sergei Rudskoi.

Lasting ceasefire evasive

United Nations envoy Staffan de Mistura said the short break would only enable the evacuation of 200 wounded persons from the devastated city.

The UN's Geneva-based humanitarian agency said "really meaningful" help would only be possible when all conflict parties gave assurances for a lasting ceasefire.

EU leaders due to meet at a summit in Brussels Thursday were expected to jointly condemn Moscow for past air raids on Aleppo, according to a draft statement obtained by AFP.

Five years of diplomatic effort have failed to put an end to Syria's conflagration.

Talks were also held Wednesday in Geneva between Russian, US, Saudi, Qatari and Turkish officials on how to distance Syrian opposition fighters from jihadists.

Turkey: air raids on YPG

The airstrikes north of Aleppo had targeted Kurdish militia in the Maarraat Umm Hawsh region, said Turkey's state-run news agency Anadolu.

It claimed that as many as 200 militia personnel had been killed.

Anadolu had reporter earlier Wednesday that the Kurdish "People's Protection Units (YPG) militia had attacked Turkish-based rebels in the region.

The Britain-based Syrian Observatory for Human Rights said it had no information on such an incident.
