The deaths of four young Turkish engineers, all within the space of 14 months during 2006 and 2007, could be connected to telepathy, according to a report from the Inspection Board of the Turkish Prime Ministry.

Four engineers working for Turkish defence giant ASELSAN died in alleged mysterious circumstances and all four deaths were recorded as suicide.

Sceptical families have, however, continued to question the cases despite reports that the men had been undergoing psychological treatment before they died.

According to 'Today's Zaman' the investigation into the deaths of the men, Hüseyin Başbilen, Halim Ünsem Ünal, Evrim Yançeken and Burhaneddin Volkan, suggests that the victims could have been directed toward the suicides by way of telekinesis, citing the work done by neuropsychology expert Nevzat Tarhan.

Nevzat Tarhan asks prosecutors not to disregard the possibility of telepathy being responsible for the headaches and severe distress that may have caused the men to take their own lives.

One of the men, Hüseyin Başbilen, was found dead in his car in August 2006, Halim Ünal died from a gunshot in January 2007, Evrim Yançeken fell from the balcony of his sixth-floor apartment nine days later and two years later another engineer at the company, Burhanettin Volkan, allegedly also killed himself.

At least two of the men were said to be working on a friend-or-foe recognition system for Turkish warplanes at the time of their suicides, a project that was brought back to debate during the Ergenekon coup trials which saw significant numbers jailed for an alleged plot to overthrow the government.

Hurriyet Daily News quotes Nevzat Tarhan saying that the headaches and distress in the men could have been sent using brainwaves from 1.5km (just under a mile) away.

The report, which has been submitted to the Ankara Chief Prosecutor's Office for further investigation, doesn't come to any conclusion over whether or not the deaths were murder or suicide.

Recently the news anchor and editor-in-chief of private Turkish broadcaster 24, Yiğit Bulut, claimed that 'certain powers' were attempting to kill controversial Prime Minister Recep Tayyip Erdoğan using telekinesis. Mr Bulut, although widely ridiculed for the comments, has since been named a chief consultant for Erdoğan.
