Iran ? A daughter of al-Qaida leader Osama bin Laden has taken refuge in the Saudi Embassy in Tehran after eluding guards who have held her, her sister and four brothers under house arrest for eight years, a Saudi-owned newspaper reported Wednesday.

It has long been believed that Iran has held in custody a number of bin Laden’s children since they fled Afghanistan following the U.S.-led invasion of that country in 2001 — most notably sons Saad and Hamza bin Laden, who are thought to have held positions in al-Qaida.

This year, U.S. officials said Saad bin Laden may have been killed by a U.S. airstrike in Pakistan, where they said he may have fled after being freed from Iran, but they could not confirm the information.

Asharq Al-Awsat said the 17-year-old daughter, Eman, slipped away from guards and fled to the Saudi Embassy nearly a month ago.
