Syria needs the world's help now more than ever, according to a leading Christian aid agency in the field.

World Help has announced today that it is delivering emergency supplies of basic food and bedding for Syrians trapped in war-ravaged Aleppo.

The aid convoy will be a "first-step" response to the crisis in the city.

Vernon Brewer, World Help president, said: "The world can no longer ignore the conflict in Syria. For more than five years, Syria has seen its children suffer in refugee camps, drown in the Mediterranean, or suffocate under the wreckage of what used to be a home. Today, more than ever, Syria needs our help."

News of the emergency delivery comes after images of five-year-old Omran Daqneesh and the death of his brother in hospital illustrated again the severity of the catastrophe.

According to aid workers, children make up more than a third of the casualties in Aleppo.

Last week, the death of Ali Daqneesh, Omran's 10-year-old brother, raised the number of children casualties in Aleppo for the month of August to 100, according to the Syrian Observatory for Human Rights.

Brewer said: "This is not a time for slow, opinionated discussions of the problem. This is a time for action, for compassion. More than 300,000 people are trapped in eastern Aleppo today, and as every day goes by, more children die. If we don't do anything about it, a whole Syrian generation will be lost.

"While pundits talk endlessly about Syria, we have decided to act, to care for everyone we can. Too many innocent men, women, and children are caught in the crosshairs of a war they didn't choose."

World Help has been actively working with Syrian refugees since the conflict started in 2011. In Jordan, Iraq, Turkey, and Greece, the organisation has provided shelter, food, counselling, and Bibles to refugees who have managed to flee the fighting. World Help has sent covert emergency convoys into active conflict zones within Syria.
