BANGKOK >> Thai authorities issued arrest warrants Wednesday for two suspects wanted in connection with a pair of small bomb blasts outside a luxury shopping mall in Bangkok that wounded one person.

Police have released blurry images of two men seen on closed-circuit camera footage close to where the homemade pipe bombs detonated Sunday at the Siam Paragon mall. One man in the footage is carrying a small bag over his shoulder.

National police spokesman Lt. Gen. Prawut Thawornsiri described the pair as “Asian-looking.” But police have given few other details and have not yet identified the pair by name.

After Prawut spoke to reporters, a Bangkok court approved arrest warrants for the unidentified men.

Police say the explosive devices were designed to cause panic, rather than death, but it’s not known why they were planted and no one has claimed responsibility.

Thailand’s military overthrew the Southeast Asian nation’s elected government in May, and analysts say the army is likely to use Sunday’s blasts as a reason to prolong martial law.

The explosions came a little more than a week after the junta-appointed legislature formally impeached former Prime Minister Yingluck Shinawatra, the leader of the ousted government, for her role in overseeing a government rice subsidy program that lost billions of dollars.
