Explosion in eastern Turkey injures six

ISTANBUL, Dec 30 (Reuters) - An explosion in a bar in eastern Turkey injured six late on Friday, local television station CNN Turk said on its Web site.

The police chief in Malatya said the explosion could have come from a percussion bomb, but that the reason for the blast was not yet known.

Ethnic separatists, leftists and Islamic militants have carried out bomb attacks in the past to gain exposure for their causes.
