Date: May 3, 2011 Source: Associated Press   Latest developments in Arab world's unrest ___ LIBYA Libyans shouting for revenge bury Moammar Gadhafi's second youngest son to the thundering sound of anti-aircraft fire, as South Africa warns that the NATO bombing that killed him would only bring more violence. Libya's leader does not attend the tumultuous funeral of 29-year-old Seif al-Arab, but older brothers Seif al-Islam and Mohammed pay their respects, amid several thousand mourners. Fierce battles continue to rage in Misrata, the besieged rebel-held city in western Libya that has been shelled daily by Libyan forces in recent weeks. At least eight people die and more than 50 are injured on Monday, according to records at one hospital in the city. ___ SYRIA Syrian troops go door-to-door in cities and towns across the nation, arresting scores of people in a campaign of intimidation aimed at crushing an uprising against President Bashar Assad's authoritarian regime, activists say. Rami Abdul-Rahman, head of the Syrian Observatory for Human Rights, says hundreds of people have been arrested over the past two days alone. ___ YEMEN Thousands of protesters take to the streets of cities across Yemen to press the embattled president to step down after he balks at signing a deal by Arab mediators to end the impoverished nation's spiraling political crisis. Security forces fire gunshots to disperse a crowd of protesters in the southern city of Aden, killing a bystander watching the march from his balcony. A woman on the street is hit in the shoulder and injured. ___ UNITED ARAB EMIRATES An activist says authorities cracking down on a small reform movement dissolve the board of a teachers association after its members signed a petition calling for an elected parliament. The step appears linked to the government's efforts to silence calls for democratic reforms in the oil-rich Gulf nation. Five democracy advocates were arrested last month and the board of a lawyers group was dissolved last week, also for signing the petition.
