This is Ahmad Hamdan. The 26-year-old activist and filmmaker lived in Eastern Ghouta, Syria.
Earlier this month, Hamdan used the hashtag #IAmStillAlive on Facebook, hoping to draw attention to the situation in his home.
After reading Hamdan's post, Syrians inside the besieged area quickly jumped on the hashtag, using it to post their images from the ground.
The humanitarian situation in the eastern Ghouta needs direct intervention from the international community @un @NRC_Egeland ... enough silence ... daily massacres, death and terror everywhere #EasternGhouta #IAMSTILLALIVE https://t.co/oiQsGFF3jM
الكوادر الطبية في الداخل مستمرون رغم الجراح ولنا الحق بالامل والحرية والامان ك باقي العالم #أناعايش IstillAlive#
The hashtag was used regularly as a way to highlight the plight of children living in Eastern Ghouta.
"For 400,000 trapped people living in underground basements and cellars, If you want to stand with us, please take a photo of yourself, like I have and post it saying:"I stand with you, #Iamstillalive" #SaveGhouta #Ghouta #Syria https://t.co/LzDKew8LkJ
In the first two months of 2018, more than 1,000 children were killed in Syria, according to the United Nations.
Ben hala hayattayım..! diyebilmenin mutluluğu Rabbim korusun sizleri #Iamstillalive #Guta
The Arabic hashtag, #انا_عايش, was also widely shared.
#أنا_عايش #Iamstillalive
And it attracted international attention.

On March 14, Hamdan was killed by an airstrike on Hamouria, activists close to him confirmed to BuzzFeed News.
Ahmad recently wrote to a friend: "I dug my grave yesterday 😊😊😊 So that I don't have to bother myself with displacement. Here is my grave" This attitude is quite common among activists & fighters in Ghouta (but not civilians). https://t.co/Cpw1BVGgGU
The messages above were sent to a close friend of Hamdan's only days before his death.
"I dug my grave yesterday," he joked. "So that I don't have to bother myself with displacement."
Qusay Nour, an activist in Eastern Ghouta, told BuzzFeed News that Hamdan had a great sense of humor and had recently been working on a black comedy series filmed in Eastern Ghouta. Nour said Hamdan is leaving behind his wife of two years, and their daughter, Naseem, who is just 8 months old.
“He is a courageous man. He offered scenes that reflected the reality of al-Ghouta in a simple way," Nour said. "He is my friend."
News of Hamdan's death made ripples across social media.
