WARSAW/VILNIUS, July 11 (Reuters) - Poland is insisting on the permanent stationing of a U.S. Patriot battery on its soil as a condition for hosting part of a anti-missile defence shield, its defence minister was quoted as saying on Friday.
Washington wants to install 10 interceptor missiles in Poland, a NATO ally, as part of the shield project, which aims to protect the United States and its allies from attack by so-called "rogue states" and terrorist groups. In return, Warsaw wants hefty U.S. investments to upgrade its air defences. Last week, Prime Minister Donald Tusk rejected as insufficient a U.S. offer to base a Patriot battery on Polish soil for just one year, but the negotiations are continuing.
The Patriot is a long-range, high-altitude, all-weather system designed to counter tactical ballistic missiles, cruise missiles and advanced aircraft.
"We want this (Patriot) battery to be placed on our territory permanently," Defence Minister Bogdan Klich told the Dziennik daily in an interview.
"Patriots are the main condition (for an agreement on the shield). We are still waiting for the results of talks (with the United States) on modernisation of our armed forces."
Klich repeated the Polish view that hosting the interceptors would increase the security risks for his country, hence the need for increased U.S. security guarantees. "Just having the installations on our soil does not strengthen our security ... Poland can become a target for attack," he said.
Klich's comments came after Iran held a series of missile tests in the Gulf, sparking a pledge from the United States that it stood ready to defend its allies. Washington accuses Tehran of trying to build nuclear weapons. Iran denies this.
U.S. Secretary of State Condoleezza Rice said on Thursday the shield would dampen any threat of an attack from Iran.
This week, Rice signed an accord with the Czech Republic on installing a tracking radar there as part of the shield project.
Russia says the project poses a direct threat to its own security and has said it would point missiles at Poland and the Czech Republic -- its former Soviet-era satellites -- if the deployment goes ahead.
The president of Lithuania, which has been mentioned as a possible alternative to host missile interceptors if talks with Poland fail, said he saw no need to base missile shield elements in the ex-Soviet republic, now a NATO member.
"Personally, I see no need for Lithuania to take responsibility on this matter," Valdas Adamkus said when asked if he would like to see elements of the missile shield in his country, although the government has said it is ready to consider the issue.
"If my decision was needed, I would probably be against the installation of such a system in Lithuania," he told his annual news conference in the capital Vilnius.
The president's office said later in a statement Lithuania would "seriously consider" hosting part of the missile shield if negotiations with Poland failed.
The start of any talks on a shield would need the approval of the State Defence Council chaired by the president, defence sources told Reuters. (Reporting by Gareth Jones in Warsaw and Nerijus Adomaitis in Vilnius)
