**UN Assembly to Vote on Syria Resolution**
The United Nations General Assembly votes Friday on a Saudi-drafted resolution on Syria, as activists report more violence .
The Britain-based Syrian Observatory for Human Rights said Friday that shelling of a Palestinian refugee camp in the capital, Damascus, Thursday killed at least 21 people. The Observatory did not say who fired the mortars.
The group also reported clashes and government attacks Friday in other areas of the country, including the provinces of Hama, Idlib and Aleppo.
The non-binding U.N. resolution would condemn both the Assad government's use of heavy weapons and the U.N. Security Council's failure to agree on measures to stop the violence.
** Clinton to Urge South Sudan to Fix Problems with Sudan**
U.S. Secretary of State Hillary Clinton has arrived in South Sudan, where she is expected to push for compromise between the world's newest country and Sudan.
Clinton is meeting Friday with South Sudan President Salva Kiir in Juba during the brief visit.
Sudan and South Sudan failed to meet a United Nations August 2 deadline to settle differences on citizenship, oil revenue, and border demarcation that remain unresolved 13 months after the two nations split. The diplomatic failure could expose both nations to economic sanctions.
A U.S. State Department official traveling with Clinton on her multi-nation African tour said the bitter divisions over territory and oil threaten to wreck the economies of both nations.
