Amos, the UN’s under-secretary-general for humanitarian affairs and emergency relief coordinator, voiced concern over the violence targeting Syrian civilians, as well as human the rights abuses they are subjected to.

Attacks on medical facilities are at their highest levels, the UN official said.

She added that vital services, including the main water pumping station in Aleppo, had been targeted, interrupting the supply of clean water.

“Almost one million people remain without safe drinking water, in temperatures as high as 50 degrees Celsius,” she said.

Last week, Paulo Sergio Pinheiro, the head of the Independent UN Commission of Inquiry for Syria, said that the al-Qaeda-linked terrorist group ISIL had committed gross human rights violations in the country.

Violence has gripped Syria for more than three years, leaving over 160,000 people dead and millions of others displaced.

According to the UN commission, there are between 10,000 and 15,000 foreigners working with militant groups and try to trigger chaos in Syria, causing great numbers of civilian casualties.

According to reports, the Western powers and their regional allies - especially Qatar, Saudi Arabia and Turkey - are supporting the militants operating inside Syria.
