Madrid Spain, Sept 10, SPA -- Using helicopters and boats, Spanish police officers and coast guard sailors searched Friday forseven people whose boat capsized as they attempted to enterEurope illegally from the Canary Islands, police said. The crew of a fishing boat alerted authorities Thursdayafter they spotted a capsized vessel in deep waters farfrom the land, said a police spokeswoman in Las Palmas,capital of the Canary Islands. Twenty-nine migrants, all from sub-Saharan African, werepulled from the water by rescuers, she said. Although thecapsized boat had no manifest, many of those saved toldauthorities that 36 people were aboard the boat when it setout. But a Madrid newspaper, El Pais, reported Friday thathopes of finding the seven missing were slim because theboat capsized so far from the coast in Atlantic Oceanwaters as deep as 1,500 meters (4,921 feet). During the summer months, thousands of Africans attempt toenter Spain illegally by sea, risking their lives either bycrossing the perilous Strait of Gibraltar to southern Spainor by sailing northwest from the Canary Islands out in theAtlantic. Many are caught and repatriated while thousands of othersmanage to slip through. A Moroccan migrant workers' association, ATIME, says some4,000 would-be migrants have drowned in the past five yearswhile trying to make such trips.--SPA1129 Local Time 0829 GMT www.spa.gov.sa/200006
