The death toll in Indonesia’s twin quake-tsunami disaster climbed to 1,424 on Thursday with time running out to rescue survivors six days after the disaster struck.

Authorities have set a tentative deadline of Friday to find anyone still trapped under rubble, at which point the chances of finding anyone alive will dwindle to almost zero.

Indonesia’s disaster agency said thousands were injured and tens of thousands – possibly hundreds of thousands – displaced from their homes.

More than 66,000 homes were destroyed or damaged by the magnitude 7.5 quake and the tsunami it spawned on Friday

And at least 600,000 children have been affected by the quake, Save the Children said, with many sleeping on the streets among ruins.
