The United Nations Special Coordinator for the Middle East Peace Process Robert Serry expressed his concern about the deteriorating state of the ceasefire between Israel and Gaza, Yedioth Aharanoth ‎reported on Thursday.“I am worried we are seeing more and more signs that the understanding on a ceasefire reached in November 2012 is eroding in both of its main requirements – the end of all hostilities and the opening of the crossings for people and goods,” he said.“During the past two months, we have seen more rockets being fired at Israel, border incidents, and Israeli retaliatory operations causing death or injury to civilians. The United Nations condemns the rise in violence, and all parties must act in accordance with international law.”
