A street in central Warsaw has partially collapsed during the construction of a subway line, with builders pumping hundreds of tons of cement under it to keep nearby buildings upright.
A water pipeline leaked early today near a station being built on the Warsaw subway's second line.
A few dozen metres of asphalt sank and an office building and an apartment building nearby shifted slightly, forcing the evacuation of about 100 residents.
It is the second leak to hit the new subway line. In August, the construction of a station on the Vistula River was halted by an unexpected leak of ground water.
