The wife and children of the deported cleric, who has been dubbed al Qaeda's European spiritual leader, follows him to Jordan.

The family of Muslim cleric Abu Qatada have left the UK and are thought to have joined him in Jordan, where he faces terror charges.
A Home Office Spokesman said: "Abu Qatada's wife and five children have now left the UK.
"The family has formally agreed to drop an outstanding application for Indefinite Leave to Remain."
The move comes after the Government finally deported the extremist to Jordan on July 7 following a decade-long legal battle that cost the taxpayer millions of pounds.
The family is said to have boarded a flight to Jordanian capital Amman, where Qatada is awaiting trial on terrorism charges, on Thursday evening.
The spokesman refused to comment on whether the family would be allowed to return if they wanted to.
It has been reported that the family have been living in a home in Stanmore, northwest London, and were receiving £800 a week in housing, council tax and other benefits.
Several weeks ago it was speculated that the radical cleric's wife and family of three girls and two boys aged between 10 and 23 would travel to Jordan and move in with relatives.
Qatada, 53, has been in a maximum security prison in Jordan since being flown out of Britain, following a lengthy battle to have him extradited.
He faces a retrial for allegedly helping plot terror attacks on an American school in Amman and on western tourists going to Jordan to celebrate the Millennium.
He was condemned to death in absentia in 1999 for conspiracy to carry out the attack on the school but the sentence was immediately commuted to life imprisonment with hard labour.
In 2000, he was sentenced in his absence to 15 years for plotting the attack on tourists celebrating the Millennium.
He originally arrived in the UK in 1993 from Jordan and claimed asylum, which he was granted a year later. He was first arrested in London in 2001, after being accused of having links to al Qaeda members in Afghanistan.
He was never convicted of an offence, but recordings of extremist speeches he made led to him being dubbed al Qaeda's spiritual leader in Europe.
The 10-year legal battle to deport the preacher cost taxpayers more than £1.7m in legal fees. It has also been estimated that providing state support for him and his family could have added up to another £3m to the Government's bill.
