A dispute between the ruler of Dubai and his estranged wife over the welfare of their two young children will play out over the next two days in a London courtroom amid reports the princess has fled the Gulf emirate.

The case beginning Tuesday in Britain's High Court pits Sheikh Mohammed bin Rashid Al Maktoum against Princess Haya, daughter of the late King Hussein of Jordan.

The princess is believed to be in Britain, where she owns a gated mansion.

The clash between Sheikh Mohammed and Princess Haya is the latest sign of trouble in Dubai's ruling family. Last year, a daughter of Sheikh Mohammed tried to flee Dubai after appearing in a 40-minute video saying she had been imprisoned.
