The father of runaway schoolgirl Misbah Rana has rejected the terms of her mother's offer to settle out-of-court.

Louise Campbell was prepared to drop her claim for full custody of her daughter if Misbah was allowed to visit her in Scotland.
However, Sajad Rana said if the girl went to the UK she would be "prevented from returning" to him in Pakistan.
The case being heard at the Supreme Court in Islamabad was adjourned until Thursday.
The 12-year-old, also known as Molly Campbell, left her mother's home in Scotland for Pakistan last August.
Ms Campbell, who lives in the Western Isles, offered to drop her claim for full custody provided she has regular contact with her daughter, who is living with her father.
This included Misbah visiting her in Scotland during summer and winter holidays and regular contact by telephone and email.
However, following Mr Rana's rejection of the offer, the custody battle for the girl is expected to resume.
In the Supreme Court, the chief justice asked the parents' solicitors to outline their cases again.
He also asked the mother's solicitor to satisfy him that if Misbah returned to Scotland that she would be brought up as a Muslim.

The chief justice adjourned the case until Thursday when he said he hopes to make a ruling.
Last week the court ruled that the schoolgirl's parents should put their proposals for access in writing.
Ms Campbell had been granted interim custody of her daughter by the Court of Session in Edinburgh last June.
However, Misbah has insisted she now wants to live with her father's family in Pakistan.
Over the weekend, Mr Rana denied reports that she is to study Islam at a controversial religious school in Islamabad.
