Thousands of people on Sunday attended the funeral of 32-year-old socialist and poet Shaimaa al-Sabbagh, who was among at least 23 people killed and 97 wounded over the weekend at rallies and vigils across Egypt to commemorate the fourth anniversary of the country’s 2011 uprising that toppled former president Hosni Mubarak.

Many of the killings were directly attributed by eye-witnesses to the country’s feared police and security forces, who have orchestrated a coordinated crackdown on political dissent which has escalated since former Defense Minister Abdel Fattah al-Sisi rose to the presidency through a military coup engineered in July 2013.

Chants of “Down with the military and the regime” and “Interior Ministry are thugs” rang through the funeral procession in Alexandria for al-Sabbagh—who leaves behind a five-year old child.

According to the Socialist Popular Alliance Party, of which al-Sabbagh was a member, she was shot at close range by police while attending a peaceful march on Saturday in Cairo to place flowers at Tahrir Square in commemoration of people killed during and following the revolution.

Witness and freelance photographer Osama Hamamm reported on Facebook that the protesters had been chanting the revolutionary slogan “Bread, Freedom, and Social Justice” when police attacked them.

“Suddenly the security forces fired several tear gas grenades and we were all amazed,” wrote Hamamm. “I did not run. I found Shaimaa El-Sabagh walking besides me along with couple of protesters that did not run away. Suddenly we found birdshots being shot… When the birdshots stopped, I stopped and looked behind and I found Shaimaa El-Sabagh falling down.”
