Two people are dead and 14 are injured following explosions on two buses in China, believed to be deliberate acts of terrorism, prompting more security concerns just weeks before the Olympics begin in Beijing.
The explosions took place about an hour apart during the peak morning traffic in the city of Kunming, about 2000 kilometres southwest of Beijing.
The first blast occurred about "about 7am" (0900 AEST) when the vehicle was at a bus stop, killing one person and injuring 10 others, a Yunnan province police statement said.
"The glass on both sides of the vehicle was all shattered and some of the seats were warped," the brief statement said.
The second blast came about an hour later on the same road and killed one person, injuring four, according to the statement.
"The cause of the explosions are under investigation," the statement said, giving no other information.
The latest incident is likely to heighten Chinese security concerns, the latest incident coming just weeks before the Olympics opening ceremony.
In May, three people died when a public bus in Shanghai burst into flames. Police blamed the incident on flammable liquids being brought aboard the vehicle but have provided no other explanation.
