Egyptian security officials said Tuesday that three people were killed in clashes between police and protesters loyal to Egypt's former president  on the first day of a key vote on Egypt's new charter.
Tuesday's clashes in the city of Sohag came mere hours after Egyptians started casting their vote on the country's new constitution , which symbolizes a major milestone in the military-sponsored political roadmap  put in place after the former Islamist president, Mohamed Morsi, was ousted from office in July.
According to the Associated Press (AP), a major security operation is currently underway across Egypt's governorates to prevent Morsi's loyalists from disrupting the constitution's vote and in anticipation of attacks carried out by Islamic miliants.
The security officials told AP that police forces opened fire on some 300 Morsi supporters  after the officers came under fire during a rally.
The officials spoke on condition of anonymity because they were not authorized to talk to media, AP reported.
