Two Latvian soldiers were killed and three were wounded in Iraq on Wednesday when a roadside bomb exploded under their Humvee, the Defense Ministry said.
Ministry spokesman Uldis Davidovs said the explosion occurred when soldiers were out on patrol, but he did not know where it happened.
The Latvian military was expected give more information about the explosion at a news conference later Wednesday.
The two soldiers were the Baltic country's first casualties in Iraq since a Latvian soldier was killed in 2004 while trying to disarm a bomb outside Baghdad.
Latvia, a small country of 2.3 million people which joined NATO 2004, has about 130 troops serving with a Polish contingent in Diwania, Iraq.
