MINSK, March 31 (Reuters) - President Alexander Lukashenko said on Friday that Russia, which has already decided to station tactical nuclear weapons in Belarus, could if necessary put intercontinental nuclear missiles there too.

In an annual address to lawmakers and government officials, Lukashenko said Moscow's plans to station nuclear arms on the territory of its close ally would help protect Belarus, which he said was under threat from the West.

"I am not trying to intimidate or blackmail anyone. I want to safeguard the Belarusian state and ensure peace for the Belarusian people," Lukashenko said.

Although Russian President Vladimir Putin said on Saturday that the tactical missiles would remain under Moscow's control, Lukashenko suggested he could use them with Russia's agreement if Belarus was threatened with destruction.

He also raised the prospect of deploying strategic nuclear weapons - intercontinental ballistic missiles that can destroy whole cities from thousands of miles away - on Belarusian soil.

Lukashenko said Belarus had enough conventional weapons to counter threats, "but if we see that behind (the threats) lies the destruction of our country, we will use everything we have".

"If necessary, Putin and I will decide and bring in strategic weapons - if needed," he said.

He offered no evidence of such a threat from the West, or of a further allegation that there were plans to invade Belarus from neighbouring Poland, a member of the U.S.-led Western NATO alliance.
