Polish officials gave varying accounts of the foreigners killed in the tragedy, in which 141 people were injured, with 76 still in hospital, including 13 foreigners.

Krzysztof Mejer, a spokesman for governor's office in Silesia, said six foreigners had been killed: one Belgian, two Czechs, a Slovak, and two Germans including a woman who also held Polish citizenship.

Later in the evening local police spokesman Andrzej Gajek said a second Slovak had been confirmed killed.

Chorzow prosecutor Bogdan Labuzek said one Romanian citizen had also been killed.

No officials were able to confirm the death of a Dutch citizen, but a Dutchman who was among exhibitors at the Pigeon 2006 show in Chorzow told AFP that his father, Dick, had died in the disaster.

"He is dead," Frederic Basch said.

"Before I was able to escape, I saw his body. I have also had confirmation from the consulate."

Basch and his father had travelled to Chorzow from Deil in the Netherlands, and had a stand exhibiting pigeon food at the show. They were among some 20 Dutch racing pigeon enthusiasts at the exhibition.

According to Mejer 18 bodies were still unidentified, some probably of foreigners, though Renata Kasprzyk, the deputy police commander at the scene in Chorzow, had earlier said the bodies of only six still had to be identified.

The German foreign ministry said Sunday that two Germans -- a 65-year-old man and a 35-year-old woman -- were killed in the disaster, and another four were injured.

The consul general of the Czech Republic, Josep Byrtus, told AFP that two Czech nationals died when the roof of the exhibition hall caved in on Saturday, and Slovakia has reported that two of its nationals were still missing.

A rescue team with a specially trained sniffer dog will search the rubble for more bodies Monday.
