Palestinian officials say a senior adviser to the government of President Mahmoud Abbas has been abducted by unidentified gunmen in the Hamas-controlled Gaza Strip.
Fatah officials say gunmen took Omar al-Ghoul from his family home in Gaza early Friday morning, only hours after he arrived there from the West Bank.
Ghoul is an adviser to Prime Minister Salam Fayyad of the West Bank-based Palestinian government, which was set up after Hamas seized control of the Gaza Strip in June.
No one has claimed responsibility for the abduction.
Separately, Palestinian medical officials say two people were killed and 35 others wounded when an explosion hit a funeral procession in Gaza.
Fatah members had organized the funeral for a militant killed in an Israeli strike Thursday.
In the past, Hamas militants had been blamed for kidnapping Fatah personnel in Gaza. Most of those abducted have been security personnel.
