MILAN – The Latest on Europe's migration crisis (all times local):
Clashes have broken out for the second time in eight days at a crowded migrant camp on the Greek island of Lesbos.
Authorities said 35 migrants were arrested Tuesday for public disturbance offences, after police used tear gas against stone throwing protesters at the Moria camp.
The demonstrators also set fires inside the camp and just outside the perimeter, according to police.
More than 14,000 migrants remain stranded on Lesbos and other Greek islands near Turkey. They are banned from traveling to the Greek mainland following an agreement between the European Union and Turkey last year to limit migration to Europe.
The United Nations' refugee agency is appealing for $421.2 million to help improve protection of refugees in sub-Saharan and North Africa and back efforts in Europe to cope with asylum seekers.
The U.N. High Commissioner for Refugees said Tuesday the plan, which incorporates previous appeals, is needed "to help provide meaningful alternatives to refugees and others undertaking dangerous journeys to Europe."
It says 2,171 refugees and migrants were reported dead or missing as they tried to cross the central Mediterranean in this year's first half, while many others are believed to have died trying to get to Libya.
UNHCR wants to strengthen protection and reception of migrants in sub-Saharan Africa and raise awareness of the risks of traveling to Libya. It wants to help train coast guard services in North Africa.
As Italians confront the pressure of new migrant arrivals with two distinct reactions — putting out the welcome mat, or erecting barricades — the country's leaders are seeking to puncture what they see as Europe's posture of offering moral support instead of concrete action.
The latest proposal has been dubbed the "nuclear option." It calls for emergency visas for migrants rescued at sea.
Italian Foreign Minister Angelino Alfano has denied reports that the numbers could reach 200,000. But other Italian officials have acknowledged the plan is under consideration, if only to gain negotiating leverage. And the threat of the visas, which would allow free movement in the Schengen area, is enough to cause concern among Italy's neighbors. Austria's foreign minister on Monday vowed to protect the border if adopted.
