MILAN - The Italian navy rescued 3,000 migrants aboard more than a dozen boats in the Mediterranean on Saturday after receiving requests for help from 22 vessels, the coast guard said.

Operations are continuing and it is still unclear where the people will be taken, a spokesman said. Europe is struggling to cope with record influx of refugees as migrants flee war in Middle Eastern countries such as Syria. The Mediterranean has become the world’s most deadly crossing point for migrants. More than 2,300 people have died this year in attempts to reach Europe by boat, according to the International Organisation for Migration. On Saturday, thousands of rain-soaked migrants stormed across Macedonia’s border as police lobbed stun grenades and beat them with batons, seeking to enforce a decree to stem their flow through the Balkans to western Europe.

Thousands of migrants stormed across Macedonia’s border on Saturday, overwhelming security forces who threw stun grenades and lashed out with batons in an increasingly futile bid to stem their flow through the Balkans to western Europe. Some had spent days in the open with little or no access to food or water after Macedonia on Thursday declared a state of emergency and sealed its borders to migrants, many of them refugees from war in Syria and other conflicts in the Middle East.

Hundreds remained in a rain-soaked no-man’s land and authorities said they would continue to enforce a regime of rationed access despite the even greater pace of arrivals from the other side in Greece.

Migrants had been pouring across the border into Macedonia at a rate of some 2,000 per day, en route to Serbia then Hungary and Europe’s Schengen zone. Some 50,000 hit Greek shores in July alone by boat from Turkey. “In this Europe, animals are sleeping in beds and we sleep in the rain,” said 23-year-old Syrian woman Fatima Hamido on entering Macedonia. “I was freezing for four days in the rain, with nothing to eat.”

Thirty-two-year-old Saeed from Syria said of the blocked border: “We know this was not Macedonia and the Macedonian police. This was the European Union. Please tell Brussels we are coming, no matter what.” The surge in numbers in recent weeks had overwhelmed the Macedonian border town of Gevgelija, testing the patience of a conservative government that faces an election in April and has for years been thwarted in its efforts to join the European Union and NATO by a dispute with Greece over Macedonia’s name.

The government lashed out at Greece, as an EU member, for letting the migrants through and in some cases aiding their passage by chartering ships to take them from inundated Greek islands to the mainland. On Friday, riot police fired tear gas and stun grenades to drive back angry crowds, in the latest flare-up in a migration crisis that has brought ripples from the conflicts of the Middle East to Europe’s shores.

Some 600 were allowed through overnight, squeezing onto a dawn train north to the Serbian border. But more kept arriving on the Greek side, converging on a filthy, chaotic strip of frontier with little sign of an organised aid effort. Some Greeks sold sandwiches and drinks to those prepared to pay. A man with a generator charged 1.5 euros to charge mobile phones.

Tired, angry and wet, one part of the crowd pushed through police lines, while others ran through open fields several kilometres from the bulk of police. Despite the scenes of squalor and chaos, of small children crying behind razor wire, the government insisted it would press on. “We will proceed as planned; we will control the border and allow as many people in as our capacities allow,” said Interior Ministry spokesman Ivo Kotevski. “You should ask the Greek authorities what their plans are.” For many Macedonians, the crisis has echoes of 1999, when hundreds of thousands of ethnic Albanians took shelter in refugee camps on Macedonia’s northern border during a war in neighbouring Kosovo, then a province of Serbia.
