A convoy of 10 United Nations aid trucks entered northwest Syria through the Bab Al-Hawa Turkish border crossing on Sunday, UNOCHA spokesperson Madevi Sun-Suon said.

The trucks from the UN’s International Organization for Migrants (IOM) carried comprehensive shelter kits, Sun-Suon said.

She said it comes after 22 UN vehicles crossed through Bab Al-Hawa on Saturday, including:

• 12 trucks from the UN High Commissioner for Refugees (UNHCR)
• 7 trucks from the World Health Organization (WHO)
• 2 trucks from the UN Population Fund (UNFPA)
• 1 truck from the UN International Children's Emergency Fund (UNICEF)

The delivery of urgent supplies to quake-hit areas of northern Syria, much of which is held by rebels, has been complicated by the country's long-running civil war.

On Sunday, the UN’s Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator, Martin Griffiths, tweeted from the Turkey-Syria border saying the people of northwest Syria “rightly feel abandoned.”

“We have so far failed the people in northwest Syria,” Griffiths said adding that his focus and obligation now is “to correct this failure as fast as we can.”
