But officials in northern Iraq said the planes had struck several villages. There were reports that one woman was killed, although this was unconfirmed.
Turkey's deputy prime minister said more strikes against "terrorists" were possible in the coming weeks.
"We, as the government, are resolute to remove this trouble from the agenda of our country," Cemil Cicek told the state-run Anatolia news agency.
Mr Cicek also called on Kurdish militants to lay down their arms and return to their homes, insisting their fight was futile.
Turkey has regularly targeted the PKK inside Iraq in recent months, but this is thought to be the first fighter jet raid outside its own territory.
Previous strikes had used artillery or helicopters.
The Turkish planes struck several targets in different areas of northern Iraq, according to reports. Private Turkish TV reports spoke of "large numbers" planes involved, with numbers ranging from 20 to 50.
The planes hit the regions of Zap, Hakurk and Avasin as well as areas in the Kandil mountains, the military said.
