Microsoft's Greek headquarters were damaged yesterday morning when arsonists attacked the building, the company confirmed.
Early on Wednesday, two security personnel were ushered out of the Athens-based building at gunpoint, after which at least two gunmen drove a van carrying gas canisters through the entrance and set fire to it, a Microsoft spokeswoman said.
"Our priority is our people and we are grateful that no one was injured and that all employees are safe," she said.
Microsoft spokeswoman Lia Komninou said on Grecian Skai TV today that staff were told not to come to work yesterday, and are unlikely to return today.
A police source told The Guardian that there have been drive-by attacks in the area, but "nothing like this," calling the situation "unprecedented." The fire brigade estimated damage to the US software giant's building to be about €60,000 (£48,000), The Guardian said.
Microsoft is awaiting the completion of the police investigation before releasing further details about the situation.
Arson attacks against banks, foreign firms, and local politicians have recently become more frequent in Greece, The Guardian said, as the country battles high unemployment and a recession made worse by foreign policies.
