Poland upset by Russian spying

The Polish government says Russia is harming relations between the two countries by continuing, and intensifying, its spying operations in Poland.

The Polish intelligence services minister, Janusz Palubicki, said the government in Warsaw was planning new measures, which he did not specify, to put a halt to Russia's activities.

He said that last year three spies had been arrested and prosecuted, and two months ago, nine Russian diplomats had been expelled.

Russia, he said, is still failing to learn the right lessons.
