26 Killed in Bombings Across Afghanistan

Military base struck

Six people were killed in a bomb attack on a base operated by Polish and Afghan forces in the eastern Afghan province of Ghazni on Wednesday, local officials and a Reuters witness said.

Another 20 people - including at least nine soldiers - died in a spate of bombings elsewhere in the country.

Violence has intensified across Afghanistan this week as Taliban insurgents seek to increase pressure on NATO contingents preparing to withdraw by the end of 2014.
