In Indonesia, rescue teams on Wednesday struggled to reach remote areas on the western coast of Java amid heavy rain after a tsunami killed nearly 430 people last weekend.

Rains lashed fishing villages along the coast, muddying roads and holding up convoys delivering heavy machinery and aid to isolated areas.

Authorities have issued a fresh warning asking people to avoid the coastal areas. Indonesia’s meteorology agency asked people to stay at least 500 meters from the coastline along the strait, which lies between the two main islands.

Nearly 1,500 people were injured and over 21,000 people have evacuated to higher ground. At least 159 people are still missing.

A state of emergency has been declared until January 4, which authorities hope will make it easier to deploy assistance.
