Turkey denies that its forces were responsible for the artillery fire that killed nine people and wounded 23 on Wednesday.

But like the government in Baghdad, the Kurdish regional authorities who organised the tour of the lunch spot in the border village of Parakh are in no doubt.

They say those killed are the latest civilian casualties of Turkey's nearly four-decade-old war against the rebels of the Kurdistan Workers Party (PKK), which has repeatedly extended across the border into northern Iraq.

It is easy to understand why this mountain village less than five kilometres (three miles) from the Turkish border is so popular with holidaymakers and day-trippers from the scorching plains of Iraq.

A mountain stream runs through the village watering a tree-lined valley that provides welcome shade from the heat.

Now the stream is filled with upturned tables and chairs from the riverside restaurants where the artillery bombardment sowed panic.

"We didn't know what to do," said shopkeeper Ali Osman. "Things were so bad that families were fleeing leaving their children behind."

Osman said that business had been good but he didn't know how much longer it could last.

"Arab tourists (from the plains of Iraq) come here a lot," said the 52-year-old, sporting traditional Kurdish dress.

"Daily we receive about 100 coachloads of day trippers and then there are those who come with their own vehicles.

"In our village there are around 35 houses. I don't think we can live here any longer. We are going to have to leave the village."
