The medical aid group Doctors Without Borders has urged the international community to rescue tens of thousands of displaced Syrians who have been stranded without food and little water in a remote desert area on the Jordanian border.

Jordan sealed the border after a June 21 suicide attack, blocking aid deliveries except for some water.

Benoit De Gryse, operations manager of the group known by its French acronym MSF, warned Thursday that if the situation continues, "we will soon see starvation, dehydration and we will be confronted with preventable deaths."

De Gryse said aid must be allowed to resume immediately and that the international community must relocate those stranded at the border to other countries.

Citing security concerns, Jordan has signaled a resumption of aid from its territory is unlikely.
