The UN's human rights chief today urged the international community to protect civilians in Syria, stating that the Security Council’s failure to agree on collective action seems to have fuelled the Government’s readiness to massacre its own people. According to local sources, as well as independent media reports from inside the city of Homs, the Syrian army has sharply increased the use of tanks, helicopters, mortars, rockets and artillery fire to attack civilian areas, stated a news release issued by the Office of the High Commissioner for Human Rights (OHCHR).
