CAIRO (AFP) - The Arab League decided on Wednesday to seek a UN Security Council resolution against Israeli settlement construction on Palestinian land. Arab foreign ministers decided to "bring up the entire situation with the Security Council and to activate the follow-up committee's decision to bring up the issue of Israeli settlements again to the Security Council." The Arab League wants "to obtain a decision that confirms, among other things, the illegal nature of this activity and that would oblige Israel to stop it," a ministerial committee meeting at League headquarters in Cairo said. The ministers, in their final statement, also urged the United States, which has traditionally vetoed Security Council resolutions against Israel, not to obstruct its decision. Arab foreign ministers said the Palestinians would not resume peace talks with Israel without a "serious offer" guaranteeing an end to the conflict, Arab League chief Amr Mussa said. Meanwhile, a senior Hamas leader said that the Arab League meeting on the stalled Israeli-Palestinian peace process on Wednesday was nothing more than "a cover for the failure" of the Palestinian Authority. "The Arab League meeting is just a cover for the failure of the Palestinian Authority (PA) in Ramallah," Mahmud Zahar told AFP in an interview. "This cover will be used for more expansion of settlements, more intensification of settlers in the West Bank, more demolitions of Palestinian houses in east Jerusalem, and more sanctions and even aggression against Gaza." Meanwhile, the Lebanese army said it dismantled two "espionage devices" on Wednesday that Israel had placed on top of two of the country's mountains, acting on an alert from Hezbollah. "Earlier today, military intelligence discovered the two devices and dismantled them," an army spokesman told AFP, without specifying the nature of the equipment. The spying devices were found on Mount Sannine, northeast of Beirut, and the Barouk Mountain, east of the capital, he added. An army statement said the device on Mount Sannine consisted of visual emission and reception parts. The second device was "more complicated," it added, without elaborating. It said the military had been alerted to their existence by Lebanon's powerful Hezbollah, which has been cooperating closely with army intelligence since the launch of a national crackdown on alleged Israeli spy rings in 2009. The Shia militant Hezbollah has accused its arch-enemy Israel of having infiltrated the country's telecom sector. Meanwhile, US envoy George Mitchell pledged to pursue "substantive" talks with Israel and the Palestinians on rescuing their battered peace process after meetings in the Egyptian capital on Wednesday. "In the days ahead our discussions with both sides will be substantive, two-way conversations with an eye towards making real progress in the next few months on the key questions of an eventual framework agreement," he told reporters. He met separately with Egypt's President Hosni Mubarak, Arab League chief Amr Mussa and Qatari Prime Minister Sheikh Hamad bin Jassem bin Jabr al-Thani as part of a US diplomatic flurry since Washington failed to secure a new Israeli settlement freeze. The Palestinians insist on a freeze as a precondition to resuming the US-brokered peace talks. Mubarak, a key regional player whose country is only one of two Arab states to have signed a peace deal with Israel, held separate talks in Cairo on Wednesday with Palestinian president Mahmud Abbas. According to Egypt's official MENA news agency, the president also received a phone call from Israeli Prime Minister Benjamin Netanyahu and they discussed the impasse in the peace process. Mitchell told reporters after his talks with the Egyptian leader that Israel and the Palestinians need to "to rebuild confidence, demonstrate their seriousness and hopefully find enough common ground on which to eventually relaunch direct negotiations." The two sides, he added, had agreed in September "to pursue a framework agreement that would establish the fundamental compromises on all permanent status issues ... (to) pave the way for a final peace treaty."
