WASHINGTON/JERUSALEM (AFP) - Egyptian President Hosni Mubarak said Friday that Israels settlement expansion must stop and voiced optimism that an historic peace accord on Middle East peace was within reach. Mubarak also praised US President Barack Obama for leading a path towards agreement in the region and said the Arab world must reciprocate with forthright leadership of its own, in an opinion column published in the US daily Wall Street Journal. An historic settlement is within reach, one that would give the Palestinians their state and freedom from occupation while granting Israel recognition and security to live in peace, he wrote. Obamas address in Cairo marked a turning point in US relations with the Muslim world, said Mubarak, whose country remains Israels closest Arab ally after signing a peace treaty in 1979, the first between an Arab state and Israel. But Israels relentless settlement expansion, which has seriously eroded the prospects for a two-state solution, must cease, Mubarak said. For their part, the Palestinians must continue to develop their institutional capacity while overcoming their division to achieve their aspirations for statehood. The ambitious agenda that Obama outlined in his Cairo address earlier this month must now be followed by forward-looking steps in order to chart a new course in Americas relationship with the Arab and Muslim world, Mubarak wrote. Meanwhile, Israeli border guards have posted videos online in which they humiliate Palestinians, including ordering a young man to sing and slap himself, Israels Haaretz newspaper reported on Friday. In one video clip posted on YouTube the man is ordered to repeatedly slap himself in the face while chanting I love the border police as off-screen border guards laugh and cheer him on. Say one hummus, one ful (fava beans), I love the border guard, the off-screen voice says. The Hebrew and Arabic phrase rhymes. Another video shows a Palestinian man sitting in what appears to be a police vehicle chanting the same song. A third clip includes still photos showing Palestinians bound and blindfolded in a room with an Israeli flag. In one of the photos an Israeli soldier is posing and smiling next to one of the detainees. The caption of the video says it was made in November 2007. Another clip shows a series of still photos of border police while in the background someone sings: Let every Arab mother know that the fate of her children is in the hands of the Company, C Company in the Old City. With protective vests and clubs we break apart gun clips on Arab mothers. The newspaper quoted an unnamed border police officer who said such behaviour was common among police serving in Jerusalem and along Israels controversial West Bank separation barrier. But border guard spokesman Moshe Finsi insisted that in recent years the number of incidents of this type has significantly decreased due to improvements in educating recruits.
