LALOMANU, Samoa — Some frightened Samoans who fled to the hills as a tsunami tore through their seaside villages vowed never to return to the coastline, while aid workers delivered water and medicine amid the growing stench of decay.

Grieving survivors began to bury their loved ones, while others gathered under a traditional meeting house to hear a government minister discuss plans for a mass funeral and burial next week.

The death toll from Tuesday's earthquake and tsunami rose to 169 Thursday as searchers found more bodies in Samoa, where 129 were confirmed dead, police commissioner Lilo Maiava told The Associated Press. Another 31 were killed in the U.S. territory of American Samoa and nine in Tonga.

Maiava said drowning appeared to be the main cause of death, and some bodies were still being plucked from the sea. Police dug others from sand, mud and debris. Maiava said the search for bodies could continue for another three weeks.

A refrigerated freight container was used as a temporary morgue for the scores of bodies at a Samoan hospital.

The United States, Australia and New Zealand sent in supplies and troops, including a U.S. Navy frigate carrying two helicopters for search-and-rescue efforts. The Hawaii Air National Guard and U.S. Air Force flew three cargo planes to American Samoa carrying 100 Navy and Army guard personnel and reservists.

Many residents who raced up hillsides as the tsunami closed in remained too scared to return to their villages. More headed to the hills Wednesday night after an aftershock shook the region.

"It's a scary feeling, and a lot of them said they are not coming to the coastal area," Red Cross health coordinator Goretti Wulf said near the flattened village of Lalomanu on the devastated south coast of Samoa's main island, Upolu. "The lesson they learned has made them stay away."

Workers at Lalomanu's makeshift emergency supply base began carting water, food, tarps and clothes to 3,000 people in the hills.

Wulf said drinking water was the most pressing problem. It is the end of Samoa's dry season, when rain is scarce, and the water pipes that supply the villages were destroyed.

Military vehicles brought food, water and medicine and medical teams gave tetanus shots and antibiotics to survivors with infected wounds.

Many survivors wore face masks to reduce the growing stench of rot.
