Protesting the lack of global condemnation for atrocities in Syria, the country's main opposition coalition said Saturday it would not attend upcoming talks in Italy, Russia and the United States, dpa reported. "Due to this shameful international position, the coalition has decided to suspend its participation in the Friends of Syria Conference of international powers due in Rome on Thursday and talks in Russia and the US," the National Coalition of Syrian Revolutionary and Opposition Forces said. The boycott decision came a day after dozens of people were reportedly killed in a missile attack by troops loyal to Syrian President Bashar al-Assad against a residential area in the northern city of Aleppo. In Cairo, Syrians staged a protest near the headquarters of the Arab League in which the head of the National Coalition Moaz al-Khatib urged the world's governments to make "serious efforts" to end the bloodshed in his country. -- SPA
