Seven years ago, it was Albanian-Macedonian tensions that brought the Republic of Macedonia to the brink of war, but given what happened in the days surrounding Macedonia's parliamentary elections last Sunday, it now appears that Albanian-on-Albanian violence poses the greatest threat to Macedonian stability.

Compared with other former Yugoslav republics, Macedonia has been quite the success story. Its declaration of independence from Yugoslavia was followed by years of relative peace. Violence flared up in 2001 when Albanian guerrilla forces launched attacks on the majority Slavic Macedonian authority, but within the year the respective Macedonian and Albanian leaderships had signed on to the Ohrid Agreement, upping protection and rights for Macedonia's 25 percent ethnic Albanian minority.  

And for the most part, Ohrid seems to have worked. Today, Macedonia is an EU candidate country, and it fell just short of a NATO membership invite (no thanks to its neighbor to the south). But rifts within the Albanian community -- between the Albanian Democratic Union for Integration (DUI) and the Democratic Party of Albanians (DPA) -- could launch the country back into pre-Ohrid bloodshed. And if that's the case, the death count has already begun.   

Violence started in the weeks leading up to Sunday's elections with clashes between DUI and DPA members but culminated yesterday when a man with a Kalashnikov reportedly threatened voters at a polling station in the majority Albanian town of Aracinovo while his men stuffed the ballot box. Other sources report that Macedonian police in Aracinovo shot three men, killing one and injuring two in a clash with six armed individuals. The DUI announced that the injured men were party members, accusing the DPA and the police of collaborating to stir up trouble. 

That the violence has largely been contained within the Albanian community is a good sign, but intra-Albanian tensions could nonetheless hamper Macedonia's future government.
