[As many as 3,000 people have been
evacuated after residents of a newly
completed tower block in Australia
reported hearing "cracking noises".
Police confirmed they had found
a crack in the 33-storey Opal Tower,
in Sydney Olympic Park, following
reports of the noise on the 10th floor.
Engineers said the high-rise tower has
moved up to 2mm, local media reported.
A 1km (0.6 mile) evacuation zone,
which also affected other buildings,
was put in place amid safety fears.]
