The three Czech soldiers killed by a suicide bomber in Afghanistan on Sunday will be buried with military honours, Defence Ministry spokesman Jan Pejšek said on Monday.
Sirens will sound nationwide in their memory at midday on Wednesday, the day on which their remains will be brought home on a special army plane.
President Miloš Zeman, the head of the Czech Armed forces, and leading political representatives will be present at the ceremony at the airport.
Since 2002 more than 9,000 Czech soldiers have served in Afghanistan. Thirteen of them were killed.
