The death toll in the floods which struck Indonesia last week has now climbed to more than 500, with rescue workers still battling to reach affected areas, BBC reported.

The floods, which were caused by a rare cyclone that had formed over the Malacca Strait, have hit three provinces and impacted some 1.4 million people, according to the government's disaster agency.

Another 500 people remain missing, while thousands more have been injured, according to BBC.
