Thai police killed an armed man who had been holed up in a house for 15 hours and who in turn killed three people and wounded three others.
Local authorities reported it.
The killer, according to local media, was a 29-year-old former national park official.
He started shooting in Phetchaburi, about 100 kilometers southwest of Bangkok, around 3 pm local time (9 am yesterday in Italy), before the police surrounded the house where he was staying.
"We proceeded step by step, starting with negotiations, but he kept fighting back and shot others," Police Lieutenant General Thanawut Wutijarasthamrong said.
"He ran into his room on the second floor and kept shooting from the window. If we hadn't had shields, my men would have been killed too."
Police found a Glock pistol and two magazines at the scene but believe the man had multiple weapons.
In Thailand the possession of weapons is widespread and in the last 12 months there has been a constantly growing number of homicides, including one of the deadliest attacks in the country's recent history: the massacre of 36 people, including 24 children, in the northeastern Nong Bua Lam Phu province.
