“I strongly condemn the use of violence in recent days that has caused many deaths both in Trat Province and especially at Rachaprasong today, which is particularly saddening and disturbing since the lives of children were lost,” Ms Yingluck said in a statement posted on her Facebook page.
“My deepest condolences are for the victims who are injured and to the relatives and friends of those who lost their lives.
“The violent incidents are terrorist acts for political gain without any regard for human life. The government will not tolerate terrorism and has ordered a full investigation by authorities to find the culprits and bring them to justice without exception.”
The embattled caretaker premier said the use of violence was not a civilised way of living and not the way of life of Thais who are naturally considerate and empthatic to fellow citizens.
“I would like to again call on all sides, that it is best to use peaceful means to resolve the political conflict through the democratic process,” she added.
The statement was posted by Ms Yingluck shortly after the PDRC secretary-general Suthep Thaugsuban addressed supporters at Pathumwan intersection and condemned the perpetrators while blaming lackeys of the Thaksin regime for the attacks.
