The BBC gives us more details on the tragedy:
The operation to recover hundreds of bodies inside a sunken Philippine ferry has been suspended after a highly toxic pesticide was found to be on board.
Ten tonnes of endosulfan were illegally in the cargo, destined for a Del Monte pineapple plantation, officials said.
Whether the ferry operator, Sulpicio Lines, knew of the toxic cargo is unclear, though a senior official warned it could face prosecution.
Only 56 of more than 850 passengers are known to have survived the disaster.
