Warsaw has promised to issue international arrest warrants for Taliban militants who executed Piotr Stanczak in Pakistan, four months after his abduction.
"A crime was committed, so there has to be an investigation, a search for the culprits, and if possible putting them before the justice system and an exemplary punishment," Foreign Minister Radek Sikorski said.
Top Polish officials have also charged elements within the Pakistani Government for the killing, the Dawn said.
Polish Law Minister, Andrzej Czuma said intelligence has identified the kidnappers of Stanczak as members of the Taliban.
He added that extremist groups in Pakistan enjoy the support of the Pakistan government.
"A lot of people among Pakistan's authorities sympathise with these bandits," Czuma said.
A Taliban spokesperson has claimed that Stanczak was killed due to Islamabad's failure to release 26 of its associates.&13;
