BANGKOK: At least four people were injured in multiple small explosions in capital of Thailand, Bangkok, on Friday ahead of a regional security summit which was attended by top diplomats from around the world.

First two blasts were heard in central Bangkok around 9:00 am, while the third one went off at a government building hosting different ministries in the metropolis. Thai Police have recovered six exploded and one unexploded bombs.

Erawan Medical Center confirmed that four people were injured, but none of them were in serious condition and they were getting medical treatment at hospitals.

Thai Prime Minister Prayuth Chan-o-cha has ordered an investigation to hunt the culprits.

The Thai capital is hosting a high-level meeting of foreign ministers of the member countries of the the Association of Southeast Asian Nations (ASEAN) and the United States, China and Russia. Secretary of State Mike Pompeo and Foreign Minister Wang Yi were representatives of the US and China respectively on this occasion.

“I would like to condemn those causing the situation which destroys peace and damages the country’s image,” the Thai PM said on Twitter.

On July 1, a powerful car bomb blast had left at least 10 people dead and wounded as many as 65 others, including nine children, in Kabul, Afghanistan’s capital.

The blast was so strong that it shook offices and houses up to a significant distance as the smoke billowed up into the sky.

Interior Ministry spokesman Nasrat Rahimi had said the blast hit a densely populated area where the Ministry of Defense’s engineering and logistics department was located, near the United States embassy. He said shortly after the bomb-laden vehicle detonated in Kabul, several gunmen entered a building and opened firing.
