Ariel Sharon and Jordan's King Abdullah have recently concluded a "secret" meeting regarding the West Bank security fence:
Jordan's King Abdullah and Israeli Prime Minister Ariel Sharon have met secretly for talks at Mr Sharon's ranch in southern Israel.
The two men spoke for several hours, Israel public radio reported.
No other details have been given, but a senior political source quoted by Israel's Haaretz paper said the meeting addressed the West Bank barrier.
The king is said to be concerned that construction of the barrier would prompt Palestinians to flee to Jordan.
Jordan has in the past criticised the route of the barrier in the West Bank.
A large Palestinian influx would threaten Jordan's delicate demographic balance, correspondents say. At least half of the country's population is Palestinian.
