Lebanon's Prime Minister Saad Hariri became the latest figure to back the online campaign to show support for a 2-month-old baby wounded in a regime attack in Syria.
Karim Abdallah, lost his left eye last month in an air strike on the besieged Damascus suburb of Eastern Ghouta and has become a symbol of resistance to Bashar al-Assad's regime.
Hariri posted a photo of himself on Twitter covering an eye under the hashtag #SolidarityWithKarim.
Thousands of Eastern Ghouta residents have been killed or injured during the five-year siege of rebel-held Eastern Ghouta.
The blockade has left the district's 400,000 residents struggling with malnutrition and has paralyzed local health care facilities.
Twitter users across the world have posted pictures with a hand over an eye to show their support.
