Over the past week, developments in Aleppo have plunged Syria back under the international lens. Even after more than five years of devastating conflict, a peaceful resolution seems far from reality for the embattled nation. There is still no mechanism for justice in Syria, which is paving the way for the perpetration of mass atrocities, a burgeoning humanitarian crisis and rampant impunity. Whilst political fatigue and discord in the UN Security Council have undermined recent accountability efforts, it's critical that the international community renews its efforts to pursue justice for the crimes committed.
