NATO has requested the Czech Republic to renew its surveillance mission of Icelandic airspace, Radio Prague reported Thursday, citing the defense ministry’s spokesman Petr Medek.

Medek said that the army is set to reveal the details at a press conference on Friday.

The Czech air force took its turn protecting Icleand’s airspace last autumn over the course of nine weeks.

Iceland is the only NATO member state with no air force of its own.
