"Greece biscuit factory fire leaves at least four dead"

At least four people have been killed after a fire broke out at a food factory near the central Greek city of Trikala, the country's fire service says.

The blaze began early on Monday at a Violanta biscuit factory, where 13 workers were on site, local media reported. Eight managed to escape.

One person remains missing, but the city's deputy mayor for civil protection, Giorgos Katavoutas, told the BBC that "there is no hope of finding any of the missing workers alive, given the force of the explosion and the fire that followed".

An investigation into the cause of the blaze is ongoing but unconfirmed reports have suggested a possible gas leak.

Television footage showed extensive damage to the factory, with part of the building destroyed, effectively splitting the structure in two. Thick smoke could also be seen billowing from the fire.

Violanta said it was "deeply saddened" by the fire.

"Today a serious incident occurred at our factory premises, during the night shift, for a currently unknown reason," Violanta said in a statement.

"We are fully cooperating with the relevant authorities and providing all available assistance."

Health minister Adonis Georgiadis earlier told the Skai news agency that six workers and a firefighter had been taken to hospital, adding that they were "in good health, mainly suffering from respiratory problems". [...]

Prime Minister Kyriakos Mitsotakis referred to the fire during opening remarks at a cabinet meeting on Monday.

"Our thoughts are with the families of the victims," he said, adding that the fire service was already investigating the circumstances of the incident" so that "responsibilities can be established".
