Jordan is increasing security at refugee camps housing Syrian refugees amid fears that the conflict in Syria may spill over on to its territory.
Security officials say groups inside Syria are infiltrating camps trying to provoke unrest.
In April, a bomb was found outside Zaatari, the largest camp in the country and the second biggest in the world.
Refugees inside Zaatari say Syrian government loyalists living in the camp are planning to create instability but rebel groups are also present.
