Gaza's Islamist rulers Hamas announced Wednesday that the blockaded territory's border with Egypt would open after a 50-day closure, telling Palestinians wishing to travel to present their passports.
Egypt has severely restricted access through the crossing in the border city of Rafah since July, when the army deposed Hamas's ally, president Mohamed Morsi of the Muslim Brotherhood.
The crossing will reopen for three days starting Saturday, Hamas's interior ministry said.
Filippo Grandi, head of the UN Palestinian refugee agency (UNRWA) urged Egypt Tuesday to allow people through Rafah, saying only a handful of Muslim pilgrims had been allowed across over seven weeks.

He also called on Israel to ease its blockade of the territory, imposed in 2006.
Many Gazans travel through Rafah to seek medical treatment outside of the impoverished Strip.
Israel controls the only other personnel crossing at Erez.
After Morsi's overthrow, the army destroyed hundreds of tunnels under the border that brought in construction materials and fuel. That caused the Strip's worst ever energy crisis, with power outages of up to 16 hours a day.
This month, Hamas described the Rafah closure as a "crime against humanity," and the UN criticised it for its effect on "the civilian population, including patients awaiting medical treatment."
