An image grab taken from a video distributed by Arbeen Unified Press office on August 29, 2013 allegedly shows United Nations (UN) arms experts collecting samples as they inspect the site where rockets had fallen in Damascus’ eastern Ghouta suburb during an investigation into a suspected chemical weapons strike near the capital. UN chief Ban Ki-moon said his investigating team would report back this week on the suspected use of chemical weapons in Syria as embattled President Bashar al-Assad vowed to resist any US strike.
