Syrian refugees arriving in Europe should form an army which can be sent back to 'liberate' their home country, instead of 'drinking coffee in the cafes of Berlin' while western soldiers face ISIS, the Polish foreign minister has said.

Witold Waszczykowski made the suggestion on Sunday, the day after French president Francois Hollande said they would carry out a 'merciless' war against ISIS in retaliation for the Paris' massacres.

Waszczykowski is part of Poland's new right-wing, eurosceptic government, which was sworn in Monday, after signalling it would take a hard line on Europe's biggest migrant crisis since World War II.

Speaking after observing a minute's silence on Sunday, Waszczykowski said: 'Hundreds of thousands of Syrians have come to Europe recently. We can help them form an army.

'Tens of thousands of young men disembark from their rubber dinghies with iPad in hand and instead of asking for drink or food, they ask where they can charge their cellphones.

'They can go to fight to liberate their country with our help.'

Waszczykowski said he was trying to avoid a situation where 'we send our soldiers to fight in Syria while hundreds of thousands of Syrians drink their coffee in (Berlin's) Unter den Linden' boulevard or in other European cities.

During the election campaign the party vowed to close Poland's doors to refugees and migrants and instead lend financial support to EU efforts at tackling the crisis.

Conflicting messages: The new prime minister has said they will honour their commitment to take in 9,000 refugees fleeing from ISIS, although the deputy foreign minister said the country would not

However, Prime Minister Beata Szydlo said Poland would honour the commitments made by the previous liberal government, which agreed to host more than 9,000 refugees in the framework of the EU's relocation plan.

'We honour all commitments,' Szydlo said, while adding however that 'the security of Poland and its citizens is paramount.'

Her reassurance came after Konrad Szymanski, deputy minister for EU affairs, said Poland would not take in refugees under the hotly contested EU redistribution programme in the wake of the Paris attacks.
