ATHENS (AFP) A Greek volunteer worker kidnapped by Afghan Taliban in northwest Pakistan seven months ago arrived in Athens on Saturday following his release from captivity earlier this week. Athanassios Lerounis was kidnapped in September near the border with Afghanistan while working as a teacher among the ethnic Kalash community in Chitral. I am very happy to step on Greek soil, a visibly thinner and emotional Lerounis told reporters at Athens International Airport. I wish to apologise for the turmoil and give great thanks to the people of Pakistan, the Greek government and the personal interest of the PM (George Papandreou), who acted as a human being and not as a politician, he said. Pakistani officials said Lerouniss seven-month abduction ordeal ended late Wednesday after he was released in Afghanistan and brought across the border into Chitral. It was a difficult task but our intelligence agencies did this job, Rahmatullah Wazir, the top administrative official in Chitral, told AFP by telephone on Thursday. A Greek negotiator on Saturday denied the Taliban had received compensation.
