Embattled Yemeni President Ali Abdullah Saleh has made his first public appearance since being wounded in an assassination attempt last month. In a televised interview from Saudi Arabia, Saleh said he would welcome a power-sharing deal but continued to reject protesters’ demands that he step down after more than 30 years in power. A United Nations mission to Yemen, meanwhile, has called on the international community to send aid to stave off a humanitarian crisis. The U.N. team says Yemen’s civilians risk becoming the victims of collective punishment without international help. Yemen’s elite Republican Guard has been accused of cutting off supplies to the capital city of Sana’a.
