Well-informed Lebanese officials said on Saturday that the Syrian side depicted the latest measures taken by Lebanon's government to control the influx of Syrian refugees as a “flagrant violation of the Lebanese-Syrian treaty that could aggravate relations between the two neighboring countries”.

Hizbullah chief Sayyed Hassan Nasrallah announced Friday that his party's fighters are maintaining full preparedness on the eastern border to confront any takfiri assault, alongside the army and security forces, noting that the inter-Christian dialogue that got underway might lead to resolving the presidential crisis.
