Dina Ali Lasloom, 24, intended to flee to Australia to escape a forced marriage, Human Rights Watch cited a Canadian witness as saying.
The witness said Lasloom approached her while in transit at the airport in Manila, saying "airport officials had confiscated her passport and boarding pass" for a Sydney-bound flight.
The Canadian said she helped Lasloom film social media videos about her plight. In one of them she said: "If my family comes they will kill me," HRW said.
Arranged marriages are the norm in Saudi Arabia, where a "guardianship" system requires a male family member, usually the father, husband or brother, to grant permission for a woman's study, travel and other activities.
"Lasloom's whereabouts are currently unknown," HRW said in a statement from Manila.
The Canadian witness, who spent several hours with Lasloom at the airport in Manila, reported that two of Lasloom's uncles arrived, the New York-based watchdog said. [AFP] Read more
