Syrian rights activists say government forces have resumed intense shelling in the opposition stronghold of Homs, while a U.N. commission said evidence shows Syrian leaders “at the highest levels” are responsible for crimes against humanity, The Voice of America informs. The independent U.N. panel said Thursday it delivered a report to the U.N. High Commissioner for Human Rights that included a confidential list of Syrian officials who could face investigation related to the government’s crackdown on a nearly year-long opposition uprising. The commission said it also had evidence of abuses by opposition forces. The violence Thursday followed a day of relentless shelling in Homs and elsewhere that killed at least 74 people, including two Western journalists.The French government identified the two reporters killed in Homs as Marie Colvin, a prominent American war correspondent working for Britain’s Sunday Times newspaper, and French photojournalist Remi Ochlik. Activists said several other journalists were wounded in the attack on a makeshift media center in the rebel-held Baba Amr district of Homs and that the center appeared to have been deliberately targeted.According to CNN, former U.N.
