Philippine rescuers board ferry 40 hours after blaze began
Thick, toxic fumes and extreme temperatures pose a challenge to rescuers who have boarded the ship.

More than 40 hours after a deadly ferry fire began, Philippine rescuers have boarded the charred remains of the MV June Aster in search of dozens of missing people.
Five people been found dead, while 43 people have been rescued, many of whom are receiving treatment in hospital. Eighty-four people remain missing.
Photos shared by the Philippine Coast Guard on Friday morning showed smoke still curling from the ferry, which had been travelling from the capital Manila to the island of Coron - though the plumes appear to have died down in fresh photos from Friday afternoon.
A local diver in Coron told the BBC on Friday that he and his team were on standby to help out and awaiting instructions from the coast guard.
