Sheikha Hala bint D'aji Al Khalifa, the former wife of Bahrain's crown prince, has died.

The state-run Bahrain News Agency announced Sheikha Hala's death early Sunday. It offered no details, and did not give her age.

The news agency described her as the "former wife" of Crown Prince Salman bin Hamad Al Khalifa. The couple had four children, including Prince Isa bin Salman Al Khalifa, who is second in line to the throne.

Sheikha Hala kept a low profile, but launched an anti-child abuse program in 2003. She also did other charity work.

Bahrain, off the coast of Saudi Arabia, is home to the U.S. Navy's 5th Fleet and a British naval base. The kingdom is in the midst of a yearslong crackdown on all dissent.
