AKIPRESS.COM - Syrian government aircraft deliberately bombed and strafed a humanitarian convoy, killing 14 aid workers and halting relief operations, U.N. investigators said on Wednesday in a report identifying war crimes committed by both sides in Syria's war, Reuters reported.

Syrian and Russian forces conducted daily air strikes on rebel-held eastern Aleppo between July and its fall on December 22, killing hundreds and destroying hospitals, they said.

Orphanages, schools and homes were "all but obliterated", panel chairman Paulo Pinheiro told a news conference.

Opposition groups shelled government-controlled western Aleppo, killing and injuring dozens, the report said. They prevented civilians from fleeing besieged eastern Aleppo, using them as human shields - a war crime.

"The scale of what happened in Aleppo is unprecedented in the Syrian conflict. Much of Aleppo, once Syria's biggest city and its commercial and culture center and a UNESCO World Heritage site, has been reduced to rubble," Pinheiro said.

He called for ensuring that "those responsible for this ruinous situation one day are brought to justice".

His team was ready to share its confidential list of suspected war criminals on all sides with a new U.N. body on Syria being set up in Geneva to prepare criminal prosecutions.

"It cannot pass without having this step toward justice, because of the great numbers of victims," panel member Carla del Ponte said.

"What we have seen here in Syria, I never saw that in Rwanda, or in former Yugoslavia, in the Balkans. It is really a big tragedy," she added. "Unfortunately we have no tribunal."
