Divers resumed their grim search for bodies on Sunday after a shipwreck disaster off a remote Italian island in which more than 300 African asylum-seekers are feared to have died. \"The search has resumed. We will be working in three teams doing two hour shift each. Because of the depth they can only stay down for six or seven minutes at most,\" Leonardo Ricci, a spokesman for the emergency services, told AFP on the island of  Lampedusa.
