Turkish ambassador to Washington Nabi Sensoy said Wednesday at a press confernec ein Washington that American-made weapons have been turning up in the hands of Kurdish terrorists. Sensoy said that the United States is not doing enough to influence Kurdish politicians in key positions in the Iraqi government to crack down on the PKK, which has been fighting for an independent Kurdistan within Turkey for decades. He said that Turkey has been pressing the United States to ensure that U.S. weapons supplied to Kurdish forces within the Iraqi army are not funneled to the PKK. Sensoy said that Turkey has been “patient” for years now, and the public needs to be shown some “concrete results.” He did not suggest that the U.S. has been supplying the PKK directly. But he accused Kurdish members of the Iraqi government of allowing the group to operate in northern Iraq and to stage cross border attacks into Turkey. U.S. officials have said they are working closely with Turkey to combat the PKK but that their focus in Iraq is in combating insurgents opposing U.S. forces. The United States considers the PKK a terrorist group and has taken steps to cut off its international financing. But U.S. officials have had few examples of success against the PKK in Iraq to point to in answering Turkish concerns. The perception in Turkey that the United States has ignored Turkish concerns about the PKK's operations in Iraq has increased pressure on the Turkish government to order military operations against the PKK in Iraq. The PKK has escalated attacks this year, killing at least 67 soldiers so far. More than 110 rebels were killed in the same period. “I think the Turkish people have shown enough patience,” Sensoy told reporters at a press breakfast. “We have to show the public some concrete results.”
