BEIRUT - Angry Syrian protesters pelted a group of opposition leaders with eggs outside Arab League headquarters in Cairo on Wednesday, preventing them from entering the building for talks with the organization's chief about the violence in Syria. In Syria itself, security forces killed at least 10 protesters at anti-government demonstrations Wednesday in Damascus and elsewhere, activists said, as the brutal crackdown continues despite Syria's agreement to an Arab League plan to stop the violence. The Cairo scuffle highlights the deep divisions within the Syrian opposition, which is struggling to overcome infighting and inexperience eight months into the uprising against President Bashar Assad's autocratic regime. The fault lines within the movement continue to hamper its efforts to topple Assad and have prevented the opposition from gaining the traction it needs to present a credible alternative to the regime. Instead, it remains deeply divided over fundamental issues, such as whether to engage in dialogue with the regime and call for foreign military intervention. The protesters in Cairo — apparently concerned the group of opposition leaders would agree to a dialogue with the Syrian government — threw eggs at a four-member delegation of the Syrian National Coordination Committee, headed by Hassan Abdul-Azim, as they tried to enter the Arab League's headquarters in downtown Cairo. Members of the delegation, who were pushed and shoved by about 100 protesters, were forced to turn back. "No to dialogue with the regime," shouted one protester, who gave only his first name, Amjad. Arab league officials said the delegation left to get a change of clothes and would return in a few hours time, but an official said later that a member of the delegation was meeting with Arab League Secretary General Nabil al-Arabi. The Syria-based National Coordination Committee is a rival to the broad-based Syrian National Council group that was formed in Turkey in October and rejects contact with the regime under the current crackdown. "What happened in Cairo is completely unacceptable behavior that plays into the hands of the regime and hurts our goals," Sada Hamzeh, a Paris-based Syrian dissident told The Associated Press. Some Syrians see the NCC, which includes veteran activists and former political prisoners, as more lenient and willing to engage in a dialogue with the Syrian leadership. The NCC's stance has prompted some anti-government protesters in Syria to carry banners reading: "The National Coordination Committee does not represent me." Members of the NCC reject the accusations, and the group's chief is adamant there will be no dialogue during the crackdown, but there have been reports of infighting and differing opinions within the group itself. Hussein al-Odat, a Damascus-based member of the NCC, said talks with members of Assad's regime were out of the question until Syria implements the first part of an Arab League plan agreed to last week by putting an end to the violence and the security crackdown. "After that, we will enter negotiations over changing the regime from its current form to a democratic, pluralistic one and negotiate on the terms of a transitional period," he told The Associated Press. He said the delegation was in Egypt in response to an invitation by Elaraby, who wanted to hear the group's views. Syria agreed to a peace plan brokered by the Arab League last week, but officials say Damascus has since failed to abide by its commitments under the plan, including to pull tanks and other armor out of cities and stop the bloodshed that the U.N. estimates has left at least 3,500 people dead. The deal includes a pledge to work on starting a dialogue with the Syrian opposition. But the violence has continued unabated — more than 100 people have been killed in the flashpoint region of Homs in central Syria in the past week — prompting Qatar's prime minister to call for an emergency meeting Saturday to discuss Syria's failure to abide by its commitments. Activists said at least 10 people were killed by security forces across Syria on Wednesday, including five who died in the Syrian capital. The British-based Syrian Observatory for Human Rights and the Local Coordination Committees, a key activist network, said the four were killed when security forces fired on a funeral for a man who was shot dead by security earlier in the day. Three others were killed in the southern village of Inkhel and two in Homs. It was not clear what action the Arab League would take if the bloodshed continues. It could isolate Syria by suspending or freezing its membership. That would be a symbolic blow to a nation that prides itself on being a powerhouse of Arab nationalism. ___ Associated Press writers Amr Nabil and Maamoun Youssef in Cairo and Albert Aji in Damascus contributed to this report.
