A small boat packed with at least 148 illegal immigrants from Africa landed Saturday on a beach in the Canary Islands, AP quoted the Interior Ministry as saying Saturday. The flimsy fiberglass vessel arrived at La Tejita beach on Tenerife's south coast around 6:30 a.m. (0530 GMT) as wind surfers were preparing to take to the sea, authorities said. The wind surfers and tourists alerted police. The Africans tried to run inland, but were rounded up and detained, a ministry spokeswoman said. One man, who was dehydrated and had hypothermia, collapsed on the beach and was taken to a hospital. The rest were treated on the scene by Red Cross mobile units. All the immigrants were males and at least six of them were minors, the spokeswoman told The Associated Press on condition of anonymity in keeping with ministry rules.
