HANOI, Vietnam (AP) — A study says more than a third of malaria-fighting drugs tested over the past decade in Southeast Asia and sub-Saharan Africa were either fake or bad quality. The study says bogus and badly made drugs are threatening to upend a decade of progress fighting the mosquito-transmitted disease. Fake drugs can lead to deaths because they contain no malaria-fighting agents. Pills without enough of the active ingredient to kill all malaria parasites are problematic because they increase drug resistance. That means the malaria organism will eventually survive medicines and render them useless.

PHNOM PENH, Cambodia (AP) — Security forces sealed off a village in eastern Cambodia and denied entry to human-rights workers a day after the fatal shooting of a teenager in the latest violent eviction aimed at clearing land for development. Human-rights workers expressed concern about the conduct of the soldiers and the safety of residents in Proma village in eastern Kratie province. About 400 police and soldiers raided the settlement after community leaders rejected demands to vacate their farmland. A 15-year-old girl was critically wounded in the confrontation and later died at a hospital. The incident is the latest fallout from widespread evictions and land grabs that have sparked unrest nationwide.

TOKYO (AP) — A strong earthquake struck off the coast of northeastern Japan last month. The U.S. Geological Survey says the magnitude-6.1 earthquake hit early on May 23 and was centered about 66 miles northeast of Hachinohe at a depth of 25 miles. Japan’s Kyodo News agency says the quake shook Aomori prefecture (state) and other areas of northeastern Japan, but no abnormalities were reported at nearby nuclear power plants. No tsunami warning was issued. A massive magnitude-9.0 earthquake and tsunami ravaged Japan’s northeastern coastline in March last year, leaving some 19,000 people dead or missing and badly damaging the Fukushima Dai-ichi nuclear plant.

KENGTUNG, Myanmar (AP) — A Myanmar negotiator says ethnic Shan rebels have agreed in a second round of talks that there will be no more fighting between the guerrillas and government troops. It is the latest reported agreement between the country’s new reform-minded government and various ethnic rebels. Negotiator Aung Min said that Shan State Army (South) leader Yawd Serk discussed enforcing a December ceasefire and eradicating drugs in eastern Myanmar, also known as Burma. He told reporters in Shan State’s capital, Kengtung, that recent clashes were a result of a misunderstanding over the firing of warning shots. President Thein Sein’s government has reached ceasefires with several ethnic rebel groups, but fierce fighting continues with the Kachin minority in the northern part of the country.
