حركة الجهاد الإسلامي في فلسطين
On 5 March 1991, EYP conducted a series of arrests of Palestinian terrorists in Athens, seizing a number of explosive devices. On 19 April 1991, Islamic Jihad Movement in Palestine militant Hashaykem Ahmed perpetrated a bombing in the city of Patras. The bombing resulted in seven fatalities and an equal number of injured. EYP had warned the central police headquarters that the leader of the local Palestinian student's union was an Islamic Jihad member and possessed weaponry on 3 April. On 16 April, EYP once again issued a communique warning of a possible Islamic Jihad attack in Patras. It was later revealed that the central police headquarters had failed to pass the information to their Patras colleagues. A connection between the perpetrators of the bombing and the Palestine Liberation Organization led to the expulsion of five Palestinian diplomats and eight other Palestinians. The level of EYP's awareness of Islamic Jihad's movements within the country led to allegations by a number of people including the former interior minister Ioannis Skoularikis that the bombing had been a false flag operation by either CIA or Mossad.
