A defense lawyer says a Bahraini court has ordered human rights activist Maryam al-Khawaja to remain in detention for a further 10 days as authorities continue to investigate her case.

Lawyer Mohammed al-Jishi said the order came at a court hearing Saturday, a week after al-Khawaja was arrested as she arrived in Bahrain to visit her activist father, who is on hunger strike to protest a life sentence he is serving in connection to his role in 2011 anti-government protests.

Al-Khawaja has dual Danish and Bahraini citizenship. She has been detained since her arrest and denies the charge of assaulting police officers at the airport.

Bahrain has faced more than three years of unrest as a Shiite-led opposition presses for greater rights from the Sunni monarchy.
