Sandy Wreaking Havoc on East Coast

At least 13 killed, millions without power

"Super-storm" Sandy has swept into the US East Coast with hurricane-force winds, bringing flooding, cutting power and claiming at least 13 lives.

Sandy caused a record surge of seawater in New York City, flooding subway and road tunnels and plunging much of Lower Manhattan into darkness.

President Obama has declared a "major disaster" in New York state, AFP says.

An estimated 50 million people could be affected by the storm, with up to one million ordered to evacuate homes.
