At least 18 people were killed and dozens wounded when a bus travelling in northeastern Thailand veered off the road and smashed into a tree, authorities said on Thursday. The accident occurred on Wednesday evening in Thailand's Nakhon Ratchasima province with the double decker bus carrying around 50 people returning home from a holiday. "There are 18 people killed, of these 12 women and six men including one boy," said Suthep Ruenthawil, chief of the Nakhon Ratchasima provincial disaster prevention and mitigation unit.. He added that 28 people are receiving treatment for injuries. Photos in local media of the accident's aftermath showed part of the bus lying on its side and officials standing beside a row of body bags. Mr Suthep said the bus driver lost control while the vehicle was going downhill, before it veered off the road and jumped a traffic island then smashed into a large tree. "The bus was torn into two parts," he said. Lt Col Pornpattana Pisitkarn from the Udomsap police station near where the accident occurred said the bus brakes appeared to have failed. <strong>____________</strong> <strong>Read more</strong> <strong><a href="https://www.thenational.ae/world/six-people-killed-in-three-car-crash-in-thailand-caused-by-wild-elephant-1.688771">At least six people killed in three-car crash in Thailand</a></strong> <strong><a href="https://www.thenational.ae/world/asia/fire-extinguisher-mishap-at-thai-bank-kills-eight-1.159361">Fire extinguisher at Thai bank kills eight</a></strong> <strong>____________</strong> Thailand's roads are some of the most lethal in the world, killing around 24,000 people each year, according to the World Health Organisation.
