On the eve of the fourth anniversary of the Arab Spring that ousted autocrat Hosni Mubarak, a female activist was shot dead in downtown Cairo, the capital of Egypt.

Shaimaa al-Sabagh, a member of the leftist Popular Alliance Party, was seen chanting "bread, freedom and social justice" along with other protestors, a popular slogan of the 2011 uprising against Mubarak, reports Haaretz. In the video that has been widely shared, a gunshot can be heard before al-Sabagh is seen with blood over her face and leaning on a male protestor.

Al-Sabbagh, a 34-year-old mother of a five-year-old son, was shot in the head while peacefully marching towards the Tahrir Square to lay a commemorative wreath of roses. She was then taken to a hospital, which declared her dead.

According to a spokesman from the health ministry, the Popular Alliance Party activist died of birdshot wounds, which were fired by police to disperse the march, explain fellow protestors.

Prime Minister Ibrahim Mahlab has vowed that al-Sabbagh's death was being investigated and that whoever committed the mistake that resulted in her death, will be punished, "whoever he may be."

A protestor was killed in the Mediterranean port city of Alexandria when around 300 supporters of the outlawed Muslim Brotherhood group held a demonstration.

Another fatal incident marking the anniversary of the Arab Spring in Egypt was the death of two suspected Islamists, who were killed when the bomb they were placing under a high voltage tower exploded.
