Several small explosions were reported in the Thai capital Bangkok, at least in three locations on Friday.
There were two explosions during the morning commute at the BTS Chong Nonsi station, one in Phra Ram 9 road and one at the government’s Changwattana building.
According to Thai media reports the incident left two cleaning workers injured.
Thai police said they were investigating the incidents.
Bangkok currently hosts foreign ministerial conferences from the Association of Southeast Asian Nations (ASEAN) and its counterparts, including from the United States, China and Russia.
Meanwhile, the Bangkok Post reported that police had to temporarily shut down Phra Ram 9 road, located outside their headquarters.
The move was taken after security cameras captured the image of a man dropping an unknown object near a fence.
Traffic police also reported the closure of part of Phra Ram 9 road, near the Thai royal police headquarters, to inspect the unidentified object.
“Members of the bombing unit were deployed to the site to check the situation, and roadblocks also caused congestion on nearby roads.
“However, the roadblock was lifted an hour later after police destroyed the explosives confirming the object was not a bomb,” police said.
