At least 24 people have been killed in Malaysia and Thailand in the worst flooding the region has seen for more than a decade.

Ten people lost their lives in northern Malaysia, where nearly 160,000 people have been forced from their homes. Rising flood water has made some roads impassable, hampering rescue efforts.

Relief goods have been flown in to help people stranded due to the torrential north-east monsoon rains, with more heavy rainfall predicted.

Malaysian Prime Minister Najib Razak toured some of the worst-hit areas over the weekend, following his return from a holiday in Hawaii.

The Prime Minister was criticised for his absence during the calamity, being photographed playing golf with US President Barack Obama.
