Among the many victims of Russian-regime attacks on opposition-held Aleppo is the last clown in Syria’s largest city.

Anas al-Basha, 24, was reportedly killed in an air strike on Tuesday in the Mash’had district.

Basha was a director of the civil society group, Space of Hope. He dressed up as a clown to bring comfort to children amid the siege and bombardment of eastern Aleppo.

On Facebook, Mahmoud al-Basha paid tribute to his brother:

The Russians and Assad regime killed my brother Anas.

Anas who refused to leave Aleppo and decided to stay there to continue his work as a volunteer to help the civilians and give gifts for the children in the streets to bring hope for them.

All what Anas wanted is to bring happiness to the children of Aleppo.

Anas is not a terrorist! He is an active member of the civil society who worked days and nights to bring a smile to the syrian children.

He lived to make children laugh and happy in the darkest most dangerous place on this world.

I was not able to say the last farewell even my family for him because of Aleppo city is under seige since 112 days.

I am proud of you my brother, GOOD BYE DEAR

May you rest in peace better [as you] brought kindness in a cruel world.
