Polish Defense Minister Radoslaw Sikorski on Thursday signed a motion for prolonging Polish troops' mission to Iraq, the PAP news agency reported.
The motion has to be adopted by the council of ministers and then be submitted to President Lech Kaczynski for approval, PAP said.
The defense ministry did not make any comments on the issue so it still remains unknown whether the mission will be prolonged for 6 or 12 months.
Earlier in the day, the head of the Polish Presidential Chancellery Aleksander Szczyglo said a decision on pulling out troops from Iraq cannot be taken suddenly.
He said a specific pullout date would depend on the internal situation in Iraq and the U.S. strategy for its presence in that country.
He cited Kaczynski as saying recently that the withdrawal process should be concluded by the end of 2007.
Poland has some 900 soldiers in Iraq who mainly train Iraqi soldiers.
