After 10 years of civil war, Syria is suffering from its worst hunger crisis to date, according to the German aid organization Welthungerhilfe.
An "alarming record" of 12 million people do not have enough to eat - almost 60 per cent of the population - the non-government group's Syria coordinator Konstantin Witschel told dpa.
The humanitarian situation in general deteriorated over the past year with refugees particularly affected.
"The situation in camps is terrible," Witschel said, after visiting the northern Syrian city of Azaz.
He said nearly all supplies in refugee camps were lacking and the winter temperatures and heavy rain were further affecting people's conditions.
"During our visit, we met 30 children who only wore sweaters and sandals in six or seven degrees Celsius," he said.
The decline in the Syrian lira had tripled food prices, Witschel added.
