SINGAPORE - Gold gained for a fifth day as unrest in Libya, and lingering concern over the effect of Japan's nuclear crisis, combined to fuel demand for the metal as a store of value.

Immediate-delivery bullion gained as much as 0.3 percent to $1,431.48 an ounce on Tuesday, near a two-week high of $1,435.01 reached on Monday.

It traded at $1,428.16 by 2:44 pm in Singapore on Tuesday.
