Prosor also stressed the connections between Syrian regime and "its evil allies" Iran and Hezbollah. "The experience and capabilities of Iran and Hezbollah in repression are on full display in Syria. They provide weapons, ammunition, training, intelligence and logistical equipment to Assad," he said.

"Assad's partners in this 'trio of terror' are not shy about discussing their role in the slaughter. Last week, Nasrallah gave a speech praising the Assad regime, calling it 'a real military partner.' And just several days ago, Iran's vice president promised the Syrian foreign minister that Iran will continue to offer its 'experience and capabilities' to Assad's killing machine."

"It is time for the international community to hold all three members of this 'trio of terror' accountable for their crimes," he concluded.
