Polish President Andrzej Duda said on Friday he has no doubts that terrorism is linked to migration.

Duda was speaking in Malta during a meeting of the so-called Arraiolos Group, which brings together presidents from EU member states.

Duda said: "There is no doubt that the growing wave of terrorism is linked to migration."

He was speaking as a bomb blast injured 22 people on a rush-hour commuter train in London on Friday, in what the British authorities were treating as a terrorist attack.

Duda said in the Maltese capital, Valletta: "If the EU is to employ -- in its internal and external relations -- far-reaching political correctness, which I would rather call a kind of naivety, then we will not solve this problem.”

Poland and Hungary have not accepted any refugees as part of an EU programme to relocate migrants fleeing the war-torn Middle East and Africa from camps in Italy and Greece.

'Security threat'

The conservative Law and Justice (PiS) government in Warsaw has said that migrants pose a security threat.

In September 2015, EU leaders agreed that each country would accept a number of migrants over two years to alleviate the pressure on Greece and Italy.

EU leaders agreed to relocate a total of about 160,000 migrants of more than 2 million people who arrived in Europe since 2015.

In late August, the Polish foreign ministry said that Poland did not agree with the logic of relocation decisions made in September 2015, but that it would continue to provide support in other areas, including by helping to protect the EU's external borders and by strengthening its humanitarian commitment.

The European Commission earlier this month threatened legal action against EU member states including Poland which refuse to accept the bloc's immigrant quota system. (pk)
