GRAN CANARIA, Spain (Reuters) - Spain will expand naval patrols around the Canary Islands and set up more migrant centres in response to a surge of arrivals from Africa, including more than 2,000 people last weekend, the regional policy minister said on Friday.Security forces will add at least three ocean-going vessels, a plane, a helicopter and a submarine to the existing fleet policing the waters between Africa’s west coast and the Spanish archipelago, Carolina Darias told a news conference in Gran Canaria. Almost 16,000 people have reached the Canary Islands after braving the Atlantic in the dangerous crossing from Africa this year - more than 10 times last year’s total - including 2,213 last weekend. “The main objective of this government, and of any government, is to avoid anybody risking their life getting aboard one of these boats,” Darias said.
