Truce plan not working

Fighting raged on in Syria yesterday, as a hoped-for ceasefire failed to materialise and Turkey intensified its shelling of Kurdish-led forces.

Further dampening hopes for an end to the conflict, the UN peace envoy admitted a February 25 date for a resumption of stalled peace talks was no longer "realistically" possible.

Key regime backer Russia meanwhile warned that recent comments by President Bashar al-Assad about retaking all of Syria were out of step with Moscow's diplomatic efforts.

On the ground, Turkey intensified its nearly week-long shelling of positions in Aleppo province, where it has sought to halt the advance of a Kurdish-led alliance against rebel forces.

The Syrian Observatory for Human Rights monitor said Ankara's overnight bombardment was the heaviest since it began targeting the Syrian Democratic Forces (SDF) on Saturday.

Turkey also expanded its fire, the Britain-based monitoring group said, hitting the Kurdish town of Afrin for the first time, where two civilians were killed and 28 wounded.

Ankara has been angered by the SDF's operation in Aleppo province, where it has seized key territory from rebel forces supported by Turkey.

Ankara considers the Kurdish People's Protection Units (YPG) that dominate the SDF to be an affiliate of the outlawed Kurdistan Workers' Party (PKK), which has waged a decades-long insurgency against the Turkish state.

Turkey president Tayyip Erdogan yesterday said there were little doubt that the YPG and PKK were behind a bombing that killed 28 people in the Turkish capital on Wednesday night, a claim denied by the Syrian Kurdish group.

Ankara fears the SDF advance in Aleppo province is intended to connect Kurdish-held areas in northern and northeastern Syria, creating an autonomous Kurdish region extending along most of its southern border.

Russia's intervention in Syria has allowed Syrian government forces to recapture key territory, including in Aleppo province, where regime fighters have virtually surrounded the rebel-held east of Aleppo city.

In an interview with AFP last week, a confident Assad defiantly pledged to retake all of Syria, but Moscow's UN envoy yesterday said that those comments were "not in accord with the diplomatic efforts that Russia is making."

Moscow backs a plan announced by 17 world powers last week for humanitarian access throughout Syria and a ceasefire that was to have begun by Friday.

But while aid deliveries have gone ahead to several besieged areas and the United Nations has said it hopes to deliver aid to all 18 within a week, there was no sign of a ceasefire being implemented yesterday.
