Egyptians are voting for a second and final day in a presidential election that is expected to bring former army chief Abdel-Fattah el-Sissi to power.
Prime Minister Ibrahim Mahlab declared Tuesday a public holiday in a push for more people to go to the polls.
Official results are not due to come out until next week, but Sissi has long been considered the likely winner in a race with leftist politician Hamdeen Sabahi as the only other candidate.
Sissi led the army's ouster of former president Mohamed Morsi last July, setting off protests from Mr. Morsi's Muslim Brotherhood and a violent military crackdown that left more than 1,000 people dead. Many of the Brotherhood's leaders have also been arrested and Sissi says the Islamist group has no future in Egypt.
The Brotherhood urged Egyptians to boycott what the group says is an illegitimate election.
