It is a national day of mourning in Zambia Monday, marking the burial of workers killed in last week's blast at a Chinese-owned explosives factory.

President Levy Mwanawasa and hundreds of mourners are expected to attend Monday's ceremony at a copper mine in the Zambian town of Chambishi, about 350 kilometers north of the capital, Lusaka.

Only the 49 bodies of workers recovered so far will be buried at the specially designed site in front of the plant.

The Zambian government and Beijing are locked in a dispute over the actual number of fatalities, with Lusaka claiming that more than 50 people died in the blast.

The explosion has also sparked accusations that the Chinese owners flouted safety rules at the BGRIMM plant, although Beijing has agreed to compensate relatives of the dead workers.
