GAZA, June 2 (Xinhuanet) -- The United Nations Relief and Works Agency (UNRWA) called on Wednesday to sue Israeli soldiers who shotand wounded two schoolchildren in the southern Gaza Strip town of Rafah.

    Israeli soldiers shot and wounded two 10-year-old Palestinian children as they were sitting in their classroom in the al-Omareya elementary school on Tuesday.

    The school, located in the Tal al Sultan neighborhood, is one ofthose run by the UNRWA in the town.

    UNRWA chief Peter Hansen called for an immediate investigation to the attack on the school and take those responsible to court.

    One of the injured children was shot in the neck and he was in serious conditions, said Palestinian medics in Rafah, adding that the other was moderately injured.

    A UNRWA statement said Wednesday that the two children were injured by the fragments of the gunshots penetrated into one of theclassrooms.

    It was the second time in less than a year that UNRWA schools were under Israeli fire, the relief agency said.

    "This is a clear violation of schools and all human rights laws and conventions," it said.

    In March last year, one of the UNRWA schools in the town of KhanYounis in the southern Gaza Strip was hit, and a 12-year-old Palestinian girl was shot in the head and became blind for life afterwards. Enditem
