Millions to remember 9/11 victims

New York and Washington are on high alert this weekend after officials received "credible" information that al-Qaida are planning to carry out further attacks to coincide with the anniversary of 9/11.

Millions around the world will tomorrow remember the victims of the September 11 terrorist attacks, a decade after fanatical extremists used hijacked US airliners to murder nearly 3,000 people.

Families and friends of those killed in the atrocity will mark the 10th anniversary at memorial events around the globe.
