Hamas will mark the anniversary of its Jan. 25, 2006 election victory, with rallies across the West Bank and Gaza Strip on Friday.
Palestinian Authority Prime Minister Ismail Haniyeh will be addressing the main rally in Hamas's Gaza City stronghold in mid-afternoon, after the main Friday prayer.
In a speech Thursday, a defiant Haniyeh said his government did not surrender to international pressure.
Hamas's election victory came in its first race for the Palestinian parliament. It won 74 of the legislature's 132 seats and ousted Abbas' Fatah Party, which had ruled exclusively since the Palestinian Authority was formed in 1996.
