A statement issued yesterday evening by a UN spokesperson in New York said Mr. Ban is concerned by reports that water supplies in the city of Aleppo were deliberately cut off by armed groups for eight days.

“The Secretary-General notes that preventing people's access to safe water is a denial of a fundamental human right,” said the statement, adding that deliberate targeting of civilians and depriving them of essential supplies is a clear breach of international humanitarian and human rights law.

While water supplies have since been restored, the Secretary-General, according to the statement, urged all parties to ensure that the water supply in Aleppo - and everywhere in Syria - is permanently restored and to refrain from targeting civilian facilities and infrastructure.

“He asks Member States and those with influence over all the parties to the conflict to remind them of their obligations,” said the statement.
