Turkish warplanes have bombed an area inside Iraq near the border with Turkey, an Iraqi Kurdish border official said.
Colonel Hussein Tamar, director of the border guard command in the Iraqi Kurdish province of Dahuk, said no one was hurt in the strikes on Tuesday, which targeted an area that was evacuated earlier this month.
A day earlier, Iraqi Kurd leaders said they were losing patience with Turkey's raids on the Kurdistan Workers' party, a separatist movement viewed as a terrorist group by Turkey.
Turkish troops have massed on the border and Turkey has increased its ground and air attacks in recent weeks.
Another Iraqi Kurd official said the air strike was "short", lasting for about 10 minutes at 12.30pm (0930 GMT). It hit the villages of Rikan, Shezee and Samjuhu in the region of al-Amadiyah near the border, he said.
"The villages were deserted," he said.
Ankara holds PKK fighters responsible for several attacks against Turkish troops.
Tensions have escalated in recent months after several Turkish soldiers were killed by PKK fighters. Turkey says it killed between 150 and 175 PKK members in its air attack on December 16.
Ragip Duran, a political analyst from Galatasaray University, told Al Jazeera that the decision to release casualty figures is nothing more than a "public relations exercise".
He said: "Independent observers are saying that there should be some reservation regarding these figures because it is late - nine days after the first air strike.
"There are so many figures and so many places [said to be the targets of the raids] but not enough precision. Both parties [the PKK and the Turkish army] are making their own PR operation."
With domestic public opinion strongly in favor of action against the separatists, the Turkish parliament sanctioned cross-border raids into Iraq earlier in the year.
Turkey says it has the right to pursue the group inside Iraqi territory.
Iraqi reaction
Tuesday's attack came despite leaders of Iraq's autonomous Kurdistan region, and the government in Baghdad, calling for an immediate halt to the raids.
Jalal Talabani, the president, said: "We are not denying that Turkey has a right to defend itself from extremists, but some of its actions are not serving any democratic purpose in Turkey or in Iraq.
"This will not benefit the relations between the two countries."
Since 1984, the PKK's fight against Turkey for Kurdish self-rule has claimed more than 37,000 lives.
The group is labeled a "terrorist organization" by Turkey, the US and the EU.
Turkey, which has the second largest army in the Nato military alliance after the US with 515,000 troops, has moved about 100,000 soldiers up to its 380km border with Iraq.
