ALEPPO - About 400 peace activists were marching Tuesday from the outskirts of Berlin towards the devastated Syrian city of Aleppo, heading down the refugee trail in reverse.
Organised by Polish journalist and blogger Anna Alboth, the "Civil March for Aleppo" aims to build political pressure to help civilians caught up in the Syrian conflict.
Carrying white flags and hiking backpacks and wearing outdoor gear against the cold and wet December weather, the marchers had on Monday left from the centre of the German capital.
Alboth told Germany's left-leaning Tageszeitung daily that only a core group of 30 activists planned to walk all the way, adding that she expected they may be blocked at the Turkish border.
"The true purpose of the march is that the civilians in Syria get access to humanitarian aid," she said. "We are marching to build pressure."
The starting point was the disused airfield of the Nazi-era Tempelhof airport, which during the Cold War became the hub for the Berlin airlift and now houses several thousands refugees from Syria, Iraq and other countries.
The marchers plan to cover around 20 kilometres (12 miles) a day and walk through the Czech Republic, Austria and several western Balkan countries to Turkey -- and then on to Syria.
It is the route into Europe that was taken last year by more than a million people, many fleeing battlefields in Syria and elsewhere in the Middle East, with the majority ending up in the top EU economy Germany.
Several thousand people have pledged on Facebook they would join at least a section of the about 3,000-kilometre (1,900-mile) trek bound for Syria's second city, which is now squarely under the control of President Bashar al-Assad's regime.
Backed by Russia and Iran, Syrian troops last week retook control of eastern Aleppo, which had been held by disparate rebel groups since mid-2012, after a devastating month-long offensive that caused tens of thousands of people to flee their homes.
Germany has pledged 15 million euros ($15.6 million) in aid to pay for medical staff and trauma counselors for the devastated city, Development Minister Gerd Mueller said.
