Top officials have called on the United Nations Security Council to take stronger action to deal with the fallout from the 26 month old Syrian civil war in which has already claimed the lives of 100,000 people.
"The extremely high rate of killings nowadays -- approximately 5,000 a month -- demonstrates the drastic deterioration of the conflict," UN assistant secretary general for human rights Ivan Simonovic told a council meeting on Syria, according to the AFP news agency.
UN High Commissioner for Refugees Antonio Guterres added that an average of 6,000 more are fleeing the country daily.
"We have not seen a refugee outflow escalate at such a frightening rate since the Rwandan genocide almost 20 years ago," Guterres said.
"This crisis has been going on for much longer than anyone feared with unbearable humanitarian consequences," he added.
Syria's UN ambassador Bashar Jaafari disputed the UN death toll figures as "unprofessionally sourced."
The Israeli army's Golani brigade recently wrapped up a two-week exercise of ground troops, special forces and air units along Israel's 81-mile-long frontier with Syria, aimed at responding to the spillover from Syria.
"Statements that were made by high ranking officials that the Syrian border will become a border with terror is something we are dealing with every day," said Lt. Col. Anan Abbas, the Golani Brigade Commander, according to CNN. "We are making sure that there will be no penetration through the northern border of Israel."
The IDF said a number of what appeared to be mortar shells struck the Golan Heights on Tuesday, causing no damage. It is uncertain as to whether the fire was intended to hit Israel, although it is believed to be spillover from the Syrian civil war.
