Authorities in Thailand have recovered an unexploded firebomb from a marketplace in central Bangkok that was reportedly left behind from last week's attacks.
"The device is timer-triggered and is attached to a power bank, the same sort that were used in last week's attacks," a police officer confirmed, explaining that it didn't function as it was "hidden underneath a pile of clothes so there was not enough oxygen for the fire".
Nine suspects have been detained so far in connection with the series of bomb explosions that rattled the Thai capital last Friday.
Deputy Prime Minister Prawit Wongsuwan confirmed that the attacks were "linked to a southern group" without revealing more details.
Six small bombs and six fire-bombs went off in the Thai capital last Friday as the city hosted a meeting of Southeast Asian foreign ministers.
