JERUSALEM (AFP) - Israeli security forces detained 22 pro-Palestinian Israeli activists on Saturday as they dispersed a protest against settlements in the occupied West Bank, protest organisers said. Two foreign activists were also detained at the protest south of Bethlehem after they and the Israelis refused orders to evacuate a closed military zone. Two people were wounded as the protest was broken up, organisers said. Dozens of activists regularly accompany three Palestinian families to the area in order to deter hardline settlers from the nearby Beit Ein settlement from attacking them while they tend their fields. A military spokesman said the army allowed the Palestinians to enter but prevented the activists, whom he accused of provoking security forces and refusing to leave the area. He added that the military had closed the area to prevent clashes between settlers and Palestinians. Meanwhile, the Rafah crossing with Egypt was opened on Saturday to allow more than 100 patients, students and visa holders to leave the besieged Hamas-ruled Gaza Strip, an official at the crossing said. The crossing was to remain open for three days, the official added. Egypt has largely complied with the restrictions, though it occasionally opens Rafah the only Gaza crossing that bypasses Israel to allow aid in and students and medical cases out. The sanctions have crippled rebuilding efforts in the impoverished territory of 1.5 million people, which was devastated by an Israeli offensive at the turn of the year in which 1,400 Palestinians and 13 Israelis were killed. In a surprise visit to the crossing Hamas Prime Minister Ismail Haniya said he hoped to see its complete re-opening. We are prepared and ready (to operate the crossing) according to arrangements undertaken with our Egyptian brothers, the Europeans, (Abbass) presidential guard and the (Hamas-run) government, he added. Meanwhile, Israel has decided to register some 13,900 hectares of land adjacent to its largest West Bank settlement, a step that could pave the way for its expansion, a newspaper reported on Saturday. The Palestinian Al-Quds newspaper published an order on Friday from the Israeli military telling Arab residents living near the massive Maale Adumim settlement outside Jerusalem to register their land within 45 days. On Saturday the newspaper reported that the order concerns some 13,900 hectares (about 34,348 acres) of land east of Maale Adumim, near the Dead Sea and the Jordan Valley. The sparsely populated desert region is mostly inhabited by Arab Bedouin tribes, who have been expelled during previous expansions of the settlement, the boundaries of which already extend to the Jordan Valley. US President Barack Obama has pressed Israel to halt all settlement activity, including the so-called natural growth in existing settlements in the occupied West Bank, in order to relaunch peace talks with the Palestinians. Israels Prime Minister Benjamin Netanyahu has said he will not build new settlements but will allow growth in existing ones, including Maale Adumim, which Israel intends to keep in any future peace deal. Israel has long sought to expand Maale Adumim westward to incorporate the so-called E-1 area of land that would link it to Jerusalem, but has frozen the project in the face of US pressure. The Palestinians have vigorously opposed any expansion into E-1, saying its incorporation into Maale Adumim would split the occupied West Bank in half and severely threaten the viability of their future state. The presence of more than 280,000 Israeli settlers in more than 100 settlements scattered across the West Bank has long been seen as one of the main obstacles to the Middle East peace process.
