Arab newspaper says WikiLeaks will expose documents showing Turkey let cash and weapons pass over its border with Iraq to Al Qaeda.

Turkey allowed weapons to be smuggled to Al Qaeda forces in Iraq, according to documents that are about to be exposed in the WikiLeaks website. This – according to a report Thursday in the London-based Arabic newspaper Al-Hayat.

The newspaper reports that WikiLeaks – which specializes in publication of classified documents – has gotten hold of classified official documents that prove that the the Turkish authorities allowed money and weapons to pass across Turkey's border with Iraq, en route to Al Qaeda terrorists in Iraq.

In addition, the documents allegedly show that Turkey was involved both directly and indirectly in carrying out terror acts in Iraq, including the blowing up of a bridge in Baghdad.

One of the reports mentioned by Al Hayat is an intelligence cable that appears to have been sent by an American intelligence agency. The cable says: “Large amounts of water have arrived from Turkey, large waves will hit Baghdad in a few hours. Some people are widening the irrigation canals.”

This message is believed to refer to the arrival of weapons from Turkey, that were intended for terror and warfare in Baghdad. Al Hayat also says that the WikiLeaks documents show that ammunition seized in a terrorist's apartment in Iraq in 2009 bore the markings “made in Turkey.”

The US is mounting a diplomatic damage control campaign as it prepares for the release of the documents. State Department Spokesman PJ Crowley said Wednesday: "These revelations are harmful to the United States and our interests. They are going to create tension in relationships between our diplomats and our friends around the world."

Crowley said the release of secret communications about foreign governments will likely the cause the US embarrassment and damage relations with other countries. "When this confidence is betrayed and ends up on the front pages of newspapers or lead stories on television or radio, it has an impact," he said.
