Fewer Syrian refugees arriving at Zaatari camp

In March, Newsround visited the Zaatari refugee camp in Jordan.

Almost half a million refugees have fled the war in Syria have escaped to neighbouring Jordan and many end up at the Zaatari camp.

Now, UN officials at the camp have told us that the number of refugees arriving has almost ground to a halt.

Nobody is sure exactly why, but heavy fighting in Syria could be the problem.
