Baku, June 21, AZERTAC
A suicide attacker driving a truck packed with explosives barreled through Syria's border with Jordan on Tuesday, setting off a blast that killed six members of the Jordanian security forces and wounded 14, according to AP.
King Abdullah II said Jordan will "respond with any iron fist" against anyone harming its borders or security, but did not lay out specifics.
Government spokesman Mohammed Momani said Jordan is sealing the border area for the time being, leaving it unclear how international aid will reach some 64,000 Syrian refugees stranded on the other side.
It was the deadliest attack along the tense border in recent memory and raised new concerns about the pro-Western kingdom's vulnerability to spillover from long-running conflicts in neighboring Syria and Iraq.
There was no immediate claim of responsibility for the assault, the third against Jordanian security installations in seven months. The previous two attacks had targeted security compounds inside Jordan.
Jordan does not yet know who is behind the attack, Momani said.
