A roadside bomb has killed a Polish soldier who was on patrol in Afghanistan.

Poland's defense ministry says the 30-year-old serviceman was killed Tuesday when his vehicle hit an improvised explosive device in Ghazni province.

Two other Polish soldiers were wounded in the blast.

Tuesday's death brings the number of Polish troops killed in Afghanistan to at least 29.

Poland has some 2,600 troops deployed in Afghanistan as part of the NATO-led force.
