Hundreds of Syrians have attended a funeral procession for those martyred in a recent deadly bomb attack outside the Syrian city of Aleppo that targeted buses carrying evacuees from the terrorist-besieged Shia Muslim-majority towns of Kefraya and al-Foua.

According to Press TV, the mourners performed prayers in the shrine of Sayyidah Zaynab, the granddaughter of Prophet Muhammad (SAWA), and laid the victims to rest in a cemetery in the town with the same name just outside the capital Damascus on Wednesday.

"Today, there will be funeral services for 52 of the dead, after they were identified. They will be buried in a cemetery near the shrine," said an organizer of the funeral.

At least 150 people, including 72 children, were martyred on April 15, when a bomb attack hit buses waiting in the terrorist-held al-Rashideen district on the outskirts of Aleppo to cross into government-controlled territory.

The evacuation was made possible under a deal struck in late March that envisaged the transfer of people holed up in Kefraya and al-Foua in Syria’s Idlib province in exchange for the evacuation of militants and their families from the government-besieged towns of al-Zabadani and Madaya in Rif Dimashq province.

There was no immediate claim of responsibility for the Aleppo bombing, but such assaults bear the hallmarks of those carried out by Takfiri terrorists operating in conflict-ridden Syria.  

Rupert Colville, a spokesperson for the Office of the United Nations High Commissioner for Human Rights, said the attack “most likely amounts to a war crime.”

Syrian mourners carried posters bearing photographs of the fatal attack, with some of them reading, "Victory blooms from your blood.”
