The complex network of flood defences erected to shield Thailand’s capital from the country’s worst floods in nearly 60 years was put to the test today as coastal high tides hit their peak but no major breaches were reported.

The death toll from Thailand’s catastrophic flooding rose to 366 today.

The governor of Bangkok issued a dramatic warning to residents of the Thai capital to prepare for floodwaters to roll deeper into the city from suburban areas already choking under the deluge.
