Weather complicates submarine search

MAR DEL PLATA, Argentina - A multinational armada of aircraft and vessels battled high winds and raging seas on Sunday as they intensified their search for a missing Argentine submarine, after apparent attempted distress calls raised hopes the 44 crew members may still be alive.

There has been no contact with the ARA San Juan, a German-built diesel-electric sub, since early on Wednesday.

An air and sea search is under way with help from countries including Brazil, Britain, Chile, the United States and Uruguay.
