STORY: Islamist militant group Hamas, rival of the Western-backed Palestinian Authority (PA), said the PA had arrested one of its senior members wanted by Israel and another gunman, in the city of Nablus.
The PA said the reason for their arrest would be published at a later time.
The PA has come under criticism from Israel and the United States for not doing enough to rein in gunmen in militant strongholds such as Nablus and the nearby city of Jenin.
Israeli Prime Minister Yair Lapid was expected to discuss the West Bank with Jordan's King Abdullah when they meet on Tuesday in New York on the sidelines of the U.N. General Assembly.
U.S.-sponsored Palestinian statehood talks with Israel collapsed in 2014. Since then, the domestic credibility of the PA has waned, while Hamas leaders regularly calling on militants in the West Bank to step up attacks on Israel.
