State Department Photo/Public Domain(WASHINGTON) — U.S. Secretary of State John Kerry on Friday called for a war crimes investigation of Russia for its role in the destruction of Aleppo, Syria.

Speaking alongside his French counterpart at the State Department, Kerry said Russia should be held accountable for what he called a “siege of innocent people.”

“Last night the regime attacked yet another hospital and 20 people were killed and 100 people were wounded. Russia and the [Bashar al-Assad] regime owe the world more than an explanation about why they keep hitting hospitals and medical facilities and children and women,” Kerry said.

“These are acts that beg for an appropriate investigation of war crimes and those who commit these would and should be held accountable for these actions. They are beyond the accidental. … This is a targeted strategy to terrorize civilians and to kill anybody and everybody who is in the way of their military objectives,” he added.

The past two weeks have seen a brutal onslaught of rebel-held parts of Aleppo by the Russian-backed Syrian regime. Bombings intensified to new levels after a failed attempt at a cease-fire over two weeks ago. In that time, human rights groups have counted hundreds of civilian deaths in Aleppo.

The U.S., which supports moderate opposition groups, said earlier this week that it had abandoned diplomatic talks with Russia to resolve the crisis. In turn, Russia warned the United States not to attack regime military positions, perceived in Washington as a threat of force.
