The evacuation concerns two Czech diplomats as well as local embassy staff, the government said.

"We are taking all steps to help our diplomats leave Afghanistan safely," Foreign Minister Jakub Kulhanek said in a statement.

"We will also take care of the local embassy staff, just like all European countries. These people served the Czech Republic and we bear full responsibility for them," Kulhanek added.

The government also reiterated its promise to help Afghan interpreters who had worked for the Czech army in Afghanistan during its deployment there.

The Czech army was part of the foreign military operation in Afghanistan from 2002 until withdrawal in June.

"I appreciate the interpreters' work. We will take care of the interpreters and their families, and we will relocate those who have shown interest to the Czech Republic," said Defence Minister Lubomir Metnar.

The government said the evacuation flights would take place in the next few days but declined to give further details citing security concerns.
