There were nearly 70 children among the 128 people killed in a suicide car bomb in Syria.
The group was made up of civilians, medics and rebel soldiers. They were all killed when a car exploded near their convoy of buses was heading out of war-torn Aleppo.
Shortly after the carnage unfolded, photographers and cameramen raced to the scene to document the attack.

Abd Alkader Habak was knocked out by the blast, but after regaining consciousness, downed his camera and went to rescue anyone left alive.
His colleagues captured the raw emotion Abd experienced as he saw the lifeless children among the other victims.
One picture shows the man on his knees wailing while a child's body is next to him.

He told CNN: "'The scene was horrible, especially seeing children wailing and dying in front of you. I was overcome with emotion. What I and my colleagues witnessed is indescribable."
Mr Habak found one child, barely clinging to life, and rushed him to medics at a waiting ambulance.
He says the child was holding his hand and looking at him. He doesn't know if the child survived.
Abd's colleague, Muhammad Alrageb, was the one who took the photos. He also helped the victims but told CNN he wanted to snap the desperate and emotional atmosphere of the moment.
Muhammad said: "I wanted to film everything to make sure there was accountability. I feel proud that there was a young journalist there helping save lives."
The bus was a part of an evacuation deal agreed to by the Syrian Government and opposition.

The photographer was also reportedly at the scene of the suspected chemical weapons attack in the country's north which killed more than 80 civilians and sparked international outrage.
It comes after three separate investigations found a US drone strike failed to take necessary precautions to minimise civilian casualties last month.
US Central Command hit what it thought was an al-Qaeda meeting location, killing dozens of terrorists. But the missile actually struck a mosque, killing at least 38 people.
The UK could soon join America in air strikes in Syria without needing parliamentary approval. according to Foreign Secretary Boris Johnson.

Mr Johnson said: "It is my belief, though I stress no such decision has yet been taken, that were such a request to be made in future, were it to be a reasonable request in pursuit of similar objectives, then I think it would be very difficult for the United Kingdom to say no."
The Foreign Secretary has also called for Russia to do more to help properly eradicate chemical weapons from Syria.
