A crippled Italian cruise ship being towed in the Indian Ocean with more than 1,000 people aboard and no air conditioning now won’t reach land in the Seychelles until Thursday, officials said.

The cruise ship company said that food, satellite phones and VHF radios would be brought to the Costa Allegra by helicopter. Photos released on Tuesday showed hundreds of people milling on the ship’s outside decks, and officials said passengers would sleep there as well instead of in their unlit cabins.
