IDF forces detained six Arabs suspected of terrorism in Judea and Samaria on Thursday.
Palestinian Authority security sources told the Ma'an News Agency that Ahmad Kawaziya, Naseem Mohammad Kawaziya and Ghareeb Amjad Kawaziya were detained from Tuqu village, south of Bethlehem.
Another man was also arrested in Tulkarem and two others were detained in the village of Samu, south of Hebron.
An IDF spokeswoman said the detainees were being held for questioning related to security matters.
The arrests come after a flurry of IDF raids targeting senior figures of the Hamas terror organization in Judea and Samaria.
Four Hamas members of the Palestinian Legislative Council were arrested by the IDF over a five day period starting last Friday.
During the raids photos of Arab members of Israel's Knesset, including MK Hanin Zoabi, hobnobbing with senior Hamas figures were found.
Two of the Hamas detainees had been hiding in a Red Cross office in eastern Jerusalem for nearly a year.
Just two months ago IDF forces and Shabak investigators broke up several Hamas terror cells in Judea and Samaria who were in the process of planning attacks on Israeli civilians.
One of those cells was behind the 23 March 2011 bus bombing in Jerusalem that left a British women dead and wounded 47.
