Officials from the Islamic Jihad movement said Thursday that Palestinian Authority security forces detained two of the movement's leaders from their homes in the city of Jenin overnight.

In a statement, officials said PA forces raided the homes of Khalid Jaradat and Tareq Qa’dan, taking the former to an unknown location and the latter to a detention facility in the northern West Bank.

Jihad officials said PA forces were tracking members in the wake of a blast in West Jerusalem that went off near the central bus station, killing one woman and injuring 30 others.

The statement called for an immediate release of the leaders, and demanded that West Bank officials cease tracking their movements.

No group has claimed the bombing in Jerusalem, though Israeli officials told the nation's Radio Israel that investigators knew who was behind the incident.

In the southern West Bank, Israeli forces detained nine from the Hebron region overnight Wednesday, and said all were "wanted for terrorist activity," while Hamas officials accused the PA of detaining two supporters in Tulkarem and Nablus.
