|Crisis Watch summarises briefly developments during the previous month in some 70 situations of current or potential conflict, listed alphabetically by region, providing references and links to more detailed information sources (all references mentioned are hyperlinked in the electronic version of this bulletin); assesses whether the overall situation in each case has, during the previous month, significantly deteriorated, significantly improved, or on balance remained more or less unchanged; alerts readers to situations where, in the coming month, there is a particular risk of new or significantly escalated conflict, or a particular conflict resolution opportunity (noting that in some instances there may in fact be both); and summarises Crisis Group’s reports and briefing papers that have been published in the last month.
Amid mounting tensions between North and South Sudan over the disputed border area of Abyei, clashes broke out between the two sides at the beginning of the month. Northern Sudanese forces invaded Abyei on 20 May and asserted control in breach of existing peace agreements. Tens of thousands are reported to have fled south. The attacks threaten renewed conflict and weaken confidence between North and South as critical post-referendum arrangements remain unresolved.
Tensions also increased over military control and the presence of armed forces in the transitional areas of Blue Nile and South Kordofan, and CrisisWatch identifies a conflict risk alert for North Sudan for the coming month.
Violence escalated further in Yemen, where military forces loyal to President Saleh battled on several fronts, renewing fears that the continued political stalemate could erupt into civil war.
President Bashar al-Assad's regime in Syria continued to use troops and tanks to violently suppress the ongoing revolt, with hundreds of protesters feared killed, thousands detained, and widespread reports of torture.
In Pakistan, the U.S. killing of al-Qaeda leader Osama bin Laden in Abbottabad at the beginning of the month again raised questions about the military's possible involvement with jihadist groups.
Local elections in Albania on 8 May proved even more troubled than anticipated as the race for the Tirana mayor's seat ended deep within the margin of error.
In Guatemala, the Mexican Los Zetas cartel killed and decapitated 27 farm workers in the northern Petén department.
In Serbia, war crimes fugitive Ratko Mladic, the Bosnian Serb military leader accused of commanding the Srebrenica massacre and the siege of Sarajevo during the 1992-95 Bosnian war, was arrested after 16 years on the run. He was extradited to The Hague, where he will stand trial for genocide, war crimes, and crimes against humanity.
