Seoul shares closed slightly higher Friday, snapping three consecutive sessions of losses, as investors hunted bargains despite the escalating tensions in the Middle East. The local currency sharply fell against the US dollar.

The benchmark Korea Composite Stock Price Index moved up 0.31 percent, or 8.02 points, to 2,569.71.

Investors have recently been moving toward safer assets amid the Middle East tensions, with some pundits anticipating Israel may soon strike oil facilities in Iran.

"The geopolitical risks in the Middle East, a hike in the crude prices and concerns over inflation will inevitably lead to a selling pressure," Kim Ji-won, an analyst at KB Securities, said.
