A UN humanitarian official visiting northwest Syria on Tuesday urged the international community to fund crucial aid programs in the war-torn country ahead of an upcoming pledging conference in Brussels. The Idlib region, Syria's last main bastion of armed opposition, hosts about three million people, many of whom are displaced from other parts of the country. Existing financing "is clearly not enough to meet the needs of the most vulnerable people", said David Carden, UN deputy regional humanitarian coordinator for the Syria crisis, from Murin in Idlib province.
