At least 28 people were injured and taken to a local hospital for treatment on Thursday after three buses collided in Singapore. All the vehicles belonged to government agencies, local reports said.

Singapore Civil Defense Force said, according to Channel News Asia, that it was informed of the accident at 9:30 a.m., local time, (9:30 p.m. EDT Wednesday), after which it dispatched three ambulances, a fire engine and three support vehicles to the accident site at Changi Road, near Masjid Kassim. The casualties were conscious and taken to the Changi General Hospital, according to the Straits Times.

"I thought something fell so I walked out to take a look and I saw that the three buses had collided. I saw a lot of smoke coming out from bus 67 which was sandwiched between two buses,” Song Choon Gee, who owns Hong Gee Trading Company, located opposite the accident site, told the Straits Times.

The accident is currently being investigated, Today Online, the website of a local newspaper, reported, adding that two of the buses belonged to SBS Transit, a public transport operator in Singapore, while the third was part of rival agency SMRT Corporation.

Tammy Tan, a spokeswoman for SBS Transit, said, according to Today Online: “Our priority is on the well-being of our commuters who are injured," adding: "We will also be rendering assistance as best we can. We would like to apologize to affected commuters for the distress and inconvenience caused. Meanwhile, we are assisting the Police in their investigations." The company also said that it plans to send teams to the hospital to help the injured.
