George,

Nothing on the BBC news, but a search on Google News found multiple stories and on a quick skim most use the official Turkish explanation:

Turkey's military said Friday that its warplanes have successfully bombed several suspected Kurdistan Workers' Party or the PKK rebel bases in northern Iraq. Turkey's state-run news agency Anatolian reported Brigadier General Metin Gurak, a military spokesman, as saying that the attack took place Thursday in northern Iraq's Zap region, which is near the border with Turkey.

Appears like a repeat of earlier strikes and no unusual. Others know the region better than I.
