The fall of the Assad regime in Syria has not solved the country’s massive humanitarian emergency, the UN Children’s Fund (UNICEF) insisted on Thursday, with some two million sheltering in the northwest unable to go back to villages and cities shattered by 14 years of war.

In an interview with UN News’s Daniel Johnson, the agency’s regional chief of communications and advocacy in the Middle East, Ammar Ammar, has been describing the dramatic scenes he saw, while on mission this week to Damascus, Aleppo, Hama and Homs.

He began with an update on Tishreen Dam in northern Syria, scene of clashes between Kurdish groups of the Syrian Democratic Forces and pro-Turkish elements of the Free Syrian Army.
