COLOMBO, Feb. 13 (Xinhua) -- The Sri Lankan government on Wednesday accused international rights groups of bias for their alleged failure to condemn the killings of students by Tamil Tiger rebels.

    Keheliya Rambukwella, the minister of Foreign Employment and the government's defense spokesman told reporters that some 14 school children had been killed as a result of recent bomb explosions blamed on Liberation Tigers of Tamil Eelam (LTTE) rebels.

    "These groups who are very quick to blame the government have remained silent on the LTTE's killing of students," Rambukwella said.

    An LTTE female suicide bomber killed 14 civilians including six students at the Colombo's busy Fort railway station on Feb. 3.

    The students from a leading Colombo school were members of the baseball team and were returning to Colombo from the central town of Kandy when caught in the explosion.

    Rambukwella said some international rights organizations are biased against the government "by not blaming the LTTE of killings they are out to discredit the sovereign government of Sri Lanka."

    Udaya Nanayakkara, military spokesman, said that 560 people including LTTE rebels, troops and civilians were killed from Jan. 31 to Feb. 12.

    "We will continue pressurizing the LTTE despite their action to create panic in other parts of the country," Nanayakkara said.
