In Syria, a partial ceasefire brokered by the United States and Russia has entered its third day, amid accusations of violations from both sides. Airstrikes by either Syria or Russian warplanes hit a number of rebel-held villages in what the Syrian opposition called a violation of the truce. Meanwhile, Russian officials accused rebel groups of violations. However, overall, the ceasefire, which is the first to be attempted in years, appears to have calmed the violence.
