A car bomb early Tuesday morning exploded in the al-Rukban refugee camp on the Jordan-Syria border, killing six and wounding 14 other Jordanian border guards, according to a statement from the Jordanian Armed Forces.
"At 5:30 am (0230 GMT) a car bomb exploded in the Rukban district opposite the Syrian refugee camp, killing or wounding several Jordanian soldiers," the statement said. The army is expected to release further details later in the day.
A source told al-Ghad newspaper that the car stormed a guard tower at the camp before throwing shells and headed into the center for refugee services, detonating explosives and killing a group of guards.
Some 50,000 people are estimated to be in al-Rukban and other informal camps in no man's land, stranded between the borders as they await entry to Jordan. Due to security concerns, Jordan admits an average of 50-100 people per day, giving priority to the elderly, sick and injured.
In a February 2 interview with the BBC, Jordan's King Abdullah warned that there were Daesh elements within the refugees waiting at the border, explaining the long wait times and security checks Syrians undergo.
Jordan previously faced criticism for the deteriorating humanitarian conditions in the border camps, as food and medical supplies ran short.
