"There is such a declaration on our part – that we are ready to participate in monitoring patrols and we have said four of our planes are available," Pawel Soloch, the head of Poland's National Security Bureau, told public broadcaster Radio Poland on Monday.
Soloch added that "for the time being there is no question of sending [Polish] troops" to Syria.
Soloch said there was no "barter" deal to send Polish F-16s to patrol over Syria in exchange for NATO beefing up its eastern flank.
