Macedonian officials said Sunday the gunmen who clashed with police over the weekend and left 22 people dead were part of an alleged "terror group" that had planned attacks targeting state institutions, sporting events and shopping malls. At least 22 people were killed, including eight police and 14 gunmen, while 37 others were wounded. Prime Minister Nikola Gruevski said the group trained both in the region and in the Middle East, but was not backed by Macedonia's ethnic Albanian minority. Officials named five leaders of the group, who were citizens of Kosovo, as founders of paramilitary cells who entered Macedonia at the beginning of May to begin attacks, according to Interior Ministry spokesman Ivo Kotevski. More than 30 members have been arrested on terrorism-related charges.
