More than 150 Kurdish rebels from the separatist Kurdistan Workers' Party (PKK) have been killed in Turkish bombing raids carried out in northern Iraq this week, the Turkish army said on Sunday.
But a PKK spokesman dismissed the figures as false, describing them as psychological warfare.
"According to initial estimates, this operation allowed us to neutralise more than 150 terrorists," said a statement on the Turkish army website.
Several senior PKK commanders may have been among the dead, the statement said, adding that the raids caused "panic among (PKK) members."
The raids in the mountainous Qandil region, which began late Thursday and continued into the night, hit 43 targets including shelters and a PKK communications centre, which were all destroyed, the army said.
PKK spokesman Ahmed Danis dismissed the death toll issued by the Turkish army and previous figures published in the Turkish media.
He told AFP that six of their fighters had been killed during the attack overnight Friday in the Qandil mountains.
"The Turkish government is indulging in psychological warfare against the people of Kurdistan and PKK," he said.
"The Turkish media is exaggerating the number of attacks and the number of people killed and wounded," he added.
The Qandil mountains straddle Iran, Iraq and Turkey and have long been a separatist haven.
Turkish warplanes have been bombing PKK positions in northern Iraq on and off since mid-December.
