A statement from the U.S.-led coalition says one soldier died after coming under direct fire by enemy forces in the country's east. Another soldier was killed in an attack in the south, also Monday.
The coalition, known as the International Security Assistance Force, provided no other details or the nationalities of the casualties.
Afghan insurgents have increased attacks in recent months, intensifying a campaign to regain territory as foreign forces draw down ahead of full withdrawal at the end of 2014.
Monday's deaths bring to nine the number of coalition deaths so far this month. Last Tuesday, six U.S. soldiers died when their Black Hawk UH-60 went down during a mission in Zabul, southern Afghanistan.
