led barracks, bridges, roads and other targets the length and breadth of Serbia, Yugoslavia‘s dominant republic, overnight but spared the capital Belgrade for only the second time in 13 days. The official news agency Tanjug said the southern Serbian town of Vranje and a suburb of the Kosovo provincial capital of Pristina were both hit by "projectiles" at 11:00 a.m (0900 GMT). "The NATO aggressor fired one projectile on Tuesday morning which hit the vicinity of Pristina at 11 a.m. … Vranje was shaken by five strong detonations which were heard from the town‘s suburbs," Tanjug said. State media dispatches did not say whether aircraft were involved in the attacks. Neither was there any indication of damage or casualties. In Belgrade, where NATO had blasted barracks, security police buildings, militarily-relevant industries and airports almost nightly since bombings began on March 24, an air raid alert was lifted at 7:40 a.m. (0540 GMT) after a quiet night. It was unclear why Belgrade was untouched this time. But NATO may have been wary of adverse propaganda on one of Yugoslavia‘s grimmest anniversaries — the devastating Nazi bombing of Belgrade on April 6, 1941. State media references to the Nazi occupation of World War Two became more frequent as the morning progressed. "At Easter on April 6, 1941, Hitler‘s Nazi aircraft attacked Belgrade unexpectedly and without a declaration of war, devastating the city," Tanjug said. "The tragic history repeats itself. Belgrade residents will mark this tragic date in their history today while hordes of neo-fascists, represented by NATO aggressors, drop their lethal burden the way they have been doing since March 24, when they launched aggression on Yugoslavia for its refusal to accept NATO occupation (in Kosovo)." Away from Belgrade, NATO hit hard from the far north to far south, reflecting alliance vows to step up its campaign against alleged mass expulsions of Kosovo‘s majority ethnic Albanians. "We conducted four waves of strikes. All planes came back safely. We haven‘t done that many before. It was our most intensive night yet," a NATO official told Reuters in Brussels. The attacks also appeared to have claimed the largest number of civilian victims to date. "So far, we found five dead. More than 30 are wounded," a police officer told Reuters on Tuesday as he walked past smouldering ruins and wrecked cars in the town of Aleksinac. Other targets included television transmission facilities, a bridge linking Serbia with Croatia and rail and road links. Tanjug reported more than 20 bombs or missiles falling around Pristina, hitting Slatina airport and a television relay station.
