UNITED NATIONS/MOG-ADISHU (AFP) - The UN Security Counil voted unanimously Thursday to authorise the African Union peacekeeping force in Somalia to stay for another year and urged it to boost its strength to 8,000 troops. Deployed in March 2007, the force known as AMISOM fields 5,300 Ugandan and Burundian soldiers and is currently charged with protecting strategic sites in the seaside capital such as the presidency, the port and the airport. The 15-member council empowered AMISOM to stay until January 31, 2011 and asked it to increase its force strength with a view to achieving (its) originally mandated strength of 8,000 troops, thereby enhancing its ability to carry out its mandate in full. The mandate expires Sunday. The council resolution also directed the force to continue assisting Somalias transitional government in developing the Somali Police Force and the National Security Force, and to help integrate Somali units trained by other UN member states or organizations inside and outside Somalia. Earlier this month, the 53-member African Union renewed AMISOMs mandate for six months. Insurgents accuse AMISOM of being an occupying force bent on introducing Christianity to Muslim Somalia. The force has also been criticized for killing scores of civilians during retaliatory shelling. Somalia has had no effective government since President Mohamed Siad Barre was forced out of power in the early 1990s. Meanwhile, Somalias Hezb al-Islam group on Thursday slapped a ban on video games in areas under its control. The organisation argued in a statement that video games, popular with Somali youth and often played in small public game centres, were destroying the countrys social fabric. Starting two days after this statements date of issue, all video game playing centres in the areas under Hezb al-Islam control should be closed and playing video games will be prohibited, it said. Video games are designed in such a way that they destroy our social traditions and for that reason, anybody found ignoring this order will be punished and equipment will be confiscated, the statement added. It was signed by Sheikh Mohamed Omar, head of propaganda for Hezb al-Islam, an insurgent group headed by influential cleric Sheikh Hassan Dahir Aweys and which controls densely-populated areas in and around Mogadishu. Video games became particularly popular in areas on the outskirts of Mogadishu housing tens of thousands of families who fled the fighting in the capital since watching films on DVDs was also banned. Children and teenagers would gather after school in small centres like cybercafes where PlayStations were wired up and a 30-minute game cost 5,000 Somali shillings (around 15 US cents). Hezb al-Islam officials ordered us to close our video gane centres so we today were closed, we dont have a choice, said Ali Hidig, a game centre owner in Elashabiyaha, a village hosting refugees on the ouskirts of Mogadishu. Young boys used to like coming here for entertainment after school but it looks like this is now a thing of the past, he told AFP. The disappointment was deep among teenage boys in the area, where movies and sports are also banned. They have basically banned everything that is fun, so we feel increasingly bored, said one of them on condition of anonymity. Hezb al-Islam and their insurgency comrades from the Al Qaeda-inspired Shebab group are implementing a very strict form of Sharia (Islamic law) in the areas they control. In recent months across Somalia, people found dancing to traditional songs have been flogged, men guilty of trimming their beards arrested and youth playing football in shorts reprimanded by religious police units.
