BANGKOK, Feb. 22 (Xinhua) -- Two students and an official were wounded when suspected insurgents detonated a bomb at Yala Rajabhat University in Thailand's southern province of Yala on Friday morning.

    A five-kilogram bomb was placed inside its Science and Technology Faculty and was detonated by remote control at around 10 a.m. (0300 GMT), according local newspaper the Nation's website.

    The victims, all female, were rushed to Yala Center Hospital.

    Kraisorn Sritrairat, dean of the university, was quoted as saying that police are still not sure who planted the bomb. However, he said he believes the attack must be staged by suspected militants.
