NATO planes bombed targets in or near at least five Serbian cities and towns late last night in the 13th consecutive days of air strikes against Yugoslavia, the official news agency Tanjug said.
Three missiles crashed into a residential area of the central town of Aleksinac, injuring at least 10 civilians, Tanjug said. Explosions shattered every window in the centre of Aleksinac and smashed the roofs of several buildings, it added.
Five big explosions buffeted Serbia's second city Nis and aircraft could be heard flying over the industrial centre 190 km south of Belgrade, it reported.
Earlier in the day, NATO missiles hit the headquarters of the Third Yugoslav Army based in Nis. The Third Army is responsible for Kosovo province where NATO is trying to stop Serbian armed violence against ethnic Albanians.
Projectiles also struck a military court and facilities in the city's industrial zone, it said.
Tanjug also reported at least five powerful explosions last night in Serbia's main northern city Novi Sad, a constant target of NATO airstrikes in recent days. Tanjug said huge flames and heavy clouds of smoke could be seen above a crude oil refinery near Novi Sad shortly after two strong detonations rocked the area. There were no immediate reports on casualties.
Aircraft also destroyed a fourth bridge over the Danube at Sombor, 200 km north-west of Belgrade, the agency reported.
The Bogejovo railway bridge links the Serbian province of Voivodina with Croatia.
Tanjug said traffic was normal on the bridge at the time of the attack, but added that it had said no information of any casualties.
Since its campaign of air strikes against Yugoslavia began NATO has also brought down two bridges at Novi Sad and one at Backa Palanka.
A Novi Sad resident told Reuters the explosions at 10.30 p.m. (2030 GMT) came from the direction of the oil refinery which was just 100 metres away from the eastern suburb of Sangaj. State television showed flames shooting into the sky.
Tanjug further reported a heavy detonation in the area of Sombor in far northern Serbia at 10.15 p.m. (2015 GMT), followed by a huge fireball spotted from the south-east part of town. Around the same time, the Gucevo area near the western town of Loznica shuddered from an explosion, Tanjug said, adding that the target may have been a television tower there.
Meanwhile, a missile dropped from a NATO aircraft has fallen on Macedonian soil without exploding, in the second such incident since airstrikes began against Yugoslavia on March 24th, a NATO spokesman said.
Maj Jan Joosten said that HARM missile, used against air defence radar systems, had fallen in the Kumanovo region of northern Macedonia, near the border with Yugoslavia.
It caused no casualties and was recovered to be destroyed at the Krivolak military base, Maj Joosten said.
"We recognise that it has been the second occurrence within a matter of days and we understandably are very concerned by this," Maj Joosten said, adding that NATO had opened an inquiry.
Another missile was found in western Macedonia near the town of Makedonski Brod shortly after the NATO air campaign began.
