Two former military barracks, one of them designated as a future refugee camp against local opposition, have been attacked by arsonists in northern Greece.

The unknown assailants set fire late Saturday to a building in the first barracks in the city of Giannitsa, 50 kilometers (31 miles) northwest of Thessaloniki. The building was being used by the city as a warehouse storing wood and paper. The building's roof and the materials inside have burned down.

Another former barracks in the city, this one completely abandoned, was burned down Sunday morning.

The mayor and city inhabitants have opposed government plans to house refugees in one of the barracks, saying they are too close to the city center and near schools. They say they have suggested other locations.

Pope Francis says a concerted response is needed to Europe's migrant problem so that countries share equally the burden of helping those fleeing war and other "inhumane" situations.

Francis is praising Greece and other countries offering "generous" help while being on the front line of the arrivals. Speaking to people in St. Peter's Square Sunday, Francis said a "concerted response can be more effective and distribute equally the weight" of helping the migrants.

He pressed for decisive negotiations by countries to achieve this and said he always keeps the "drama of the refugees" in his prayers.

Francis also welcomed the news of the cease-fire in Syria with hope and invited prayers so this development might bring relief to those suffering from the civil war and lead to peace.
