Jordan says it has arrested a group of Hamas activists planning attacks in the kingdom, allegedly on orders from a military leader of the Palestinian militant group based in Syria.
A government spokesman in Amman says the plot was in its final stages when the suspects were seized, and that they had planned to attack senior Jordanian officials and strategic points in the kingdom.
Tuesday's announcement did not identify those in custody or how many were detained.
Last week, Jordan said it seized a cache of weapons that Hamas activists had smuggled in from Syria, and Amman cancelled a visit by the foreign minister of the Palestinian government, which is led by Hamas.
Hamas protested the snub and said it has never targeted any country other than Israel.
Jordan has long accused Damascus-based Palestinian militant groups of smuggling weapons into the kingdom. In most cases the arms were intended for use in attacks against Israel.
