UN High Commissioner for Human Rights Zeid Ra’ad Al Hussein [official profile] on Friday warned [press release] Syria that air strikes, shelling and use of toxic agents in Eastern Ghouta likely constitute war crimes.

Zeid asserts that the citizens of Eastern Ghouta are enduring every kind of deprivation, with no aid getting through since November, except for one single convoy of humanitarian aid that managed to reach just 7,200 people, of the hundreds of thousands in the area. “As a direct result, thousands upon thousands of children in Eastern Ghouta are acutely malnourished and profoundly traumatised. And now they are facing one of the most pitiless onslaughts in this long-running and brutal civil war.”

Six days ago, the UN Security Council adopted Resolution 2401 (2018) [PDF, text], that requires all parties to the Syrian conflict to immediately cease hostilities for at least 30 consecutive days, to enable the delivery of humanitarian assistance and evacuation of the critically sick and wounded. Despite the resolution, civilians in Eastern Ghouta have reported that airstrikes and shelling continue.

Zeid states that Syria must be referred to the International Criminal Court.

“Attempts to thwart justice, and shield these criminals, are disgraceful. I also urge all States to greatly increase their support for the International, Impartial and Independent mechanism [IIIM] set up last year. The IIIM’s mandate focuses on ensuring that information about serious crimes is collected, analyzed and preserved, with a view to furnishing dossiers for future prosecutions.”

Zeid believed that such process will prevent further horrific human suffering and increase the certainty that justice will one day be done.
