• BEIRUT (AP) -- A U.N. report on Syria said Tuesday there are "reasonable grounds" to believe that limited quantities of toxic chemicals have been used as weapons in at least four attacks in Syria's civil war, but said more evidence is needed to determine the precise chemical agents used or who used them.
• The U.N. Commission of Inquiry said conclusive findings can be reached only after testing samples taken directly from victims or the site of the alleged attacks. It called on Damascus to allow a team of experts into the country.
• The commission's report to the Human Rights Council on violations in Syria's conflict accused both sides of committing war crimes. In an apparent message to European countries considering arming Syrian rebels, the report warned that the transfer of arms would heighten the risk of violations, leading to more civilian deaths and injuries.
• "War crimes and crimes against humanity have become a daily reality in Syria where the harrowing accounts of victims have seared themselves on our conscience," the report said. "There is a human cost to the increased availability of weapons," it added.
• U.N.-Secretary General Ban Ki-moon has appointed a U.N. team to investigate alleged chemical weapons attacks in Syria after the Syrian government asked him to investigate a purported attack by rebels on March 19 on Khan al-Assal village in the northern city of Aleppo. But the Syrian government insists that a probe be limited to that incident.
