NATO member Poland is ready to send four F-16 warplanes to fight ISIL terrorist group, a senior defense official said Monday.

The move came after NATO signaled last week it was considering joining the U.S.-led coalition fighting the terrorists.

"We're ready to take part in patrols and have proposed four warplanes," presidential security advisor Pawel Soloch told Polish Radio, while ruling out any troop deployment.

Soloch said the Polish offer was "an expression of solidarity with our allies", adding that "Poland expects the same solidarity" from NATO regarding security along its eastern flank.
