The United States, Russia and Jordan agreed previous year to create a "de-escalation zone" in southwest Syria, which included the regions of Deraa, Quneitra and Sweida. However, by allowing Syrian President Bashar Assad's forces to re-take the south of the country, Israel is taking part in a move that de-facto allows Assad to regain control over all of Syria.
Along with Idlib province in the north, Daraa is one of the last areas of territory still held by rebels after a Syrian government push to recapture areas lost during the seven-year war.
Sources added that Bolton and Ben-Shabat will also discuss joint military cooperation in countering Iran's presence in Syria.More news: Warriors power past Rockets, set up NBA Finals showdown with Cavs

His European tour follows the United States withdrawal from the 2015 nuclear deal which the European signatories, France, Germany and Britain, have said they will stick to.
"These things, of course, reflect not only our position. This will be the main focus of my discussions", Netanyahu said. What could be causing the US' "concern" is that Dara'a borders the occupied Golan Heights which Israel has used to treat wounded militants for years. The Iranians denied they had fired any rockets.More news: Starbucks stores to shut down Tuesday for bias training
