ATHENS — Hours of heavy rainfall in Athens have caused extensive flooding, inundating basements and forcing authorities to close major roads and a central subway station.

The Greek fire brigade says it received more than 600 calls to pump out water in the greater Athens region Friday. No injuries have been reported.

Police closed underpasses and highways in low-lying parts of the city after they were submerged in floodwaters, while parked cars were swept away by racing waters.

The capital's tram system had to be shut down, while urban rail schedules were disrupted after a tree fell on the tracks.
