Police Director: Some 15 to 20kg of explosives were used in the attack last night.

Kosovo police have called an extraordinary media conference, following last night's attack on the Iber Lepenc channel in Zubin Potok.

Kosovo Police Director Gazmend Hoxha and Interior Affairs Minister Jedal Svecla have emerged at this conference.

Hoxha has said that in the past six months alone, six cases of explosions have been recorded in Serb-run municipalities north of the country.

He has said that last night's attack on Zubin Potok has been by a good organised group that knows the use of explosive devices.

Among other things, Hoxha told the media that a considerable amount of explosives, some 15 to 20kg, were used in the attack.
