(Adds PKK comment, details and background)
ISTANBUL, April 23 (Reuters) - At least four Turkish military jets bombed Kurdish separatist targets inside northern Iraq on Wednesday, a Turkish military source said.
The bombing, which lasted approximately 30 minutes, occurred between 1300 and 1400 GMT, the source said, adding that no further information on casualties was immediately available.
A spokesman for the Kurdistan Workers Party (PKK) guerrilla group said the Turkish planes bombed a remote part of northern Iraq but no one was hurt.
The Turkish military launched an eight-day air campaign in northern Iraq in February against the PKK, which uses northern Iraq to launches attacks against Turkey.
Ankara blames the separatist group for the deaths of 40,000 since 1984, when the group took up arms to carve out an ethnic homeland in southeast Turkey.
The United States and the European Union, along with Turkey, consider the PKK a terrorist organisation. (Editing by Sami Aboudi)
