Polish Foreign Minister Radoslaw Sikorski says Warsaw has not yet made a definite decision on the planned U.S. missile defense system for Poland.
Sikorski said in an interview with Gazeta Wyborcza on Saturday that Poland does not fear any threat from Iran. He added that his country also wants to avoid worsening relations with Russia.
But he said the U.S. is an important ally and its request for help must be taken seriously.
The United States wants to deploy 10 interceptor missiles in Poland and a corresponding radar system in the neighboring Czech republic. The U.S. says the missile shield is intended to protect Europe against possible attacks from Iran.
Russia is strongly opposed to the plan.
Sikorski said any agreement with the U.S. on the deployment of interceptors would need parliament's approval.
Sikorski said Polish lawmakers would have to see clear security benefits before agreeing to the U.S. plan.
Poland has scheduled talks with Russian and Czech officials on the controversial project.
Sikorski said the U.S. has not done enough to ease Russia's concerns that the missile shield would threaten its security. Russia has threatened to aim its own missiles at targets inside Poland.
