Israeli forces arrested five Palestinians in the West Bank early Saturday, including three security forces, security sources said, Xinhua reported.
Two of the detained work for the National Security Forces and the third was a member of the military police, said the sources who refused to be identified because they are not authorized to speak to the media.
The three security forces and two civilians were arrested in the northern West Bank city of Qalqilya, according to the sources.
On Friday, the Israeli army arrested five Palestinian National Authority (PNA) intelligence officers in the nearby town of Salfeet, for the first time in about three years.
Israel raids the West Bank towns on a daily basis and arrests people suspected of being affiliated with armed groups. However, it has rarely arrested people affiliated with the PNA security services.
The detention of security forces in two successive incidents angered the PNA.
"Israel tries to weaken our capabilities to undermine our security plans," said Adnan al-Dumiri, spokesman for the Palestinian security services.
"The arrests are intended to support the Israeli allegations that the Palestinian people don't deserve a statehood since they are unable to control themselves," al-Dumiri told reporters.
Peace talks between the PNA and Israel have come to a stop since December 2008 when Israel launched a major military operation in the Gaza Strip.
Efforts to renew the negotiations have so far failed due to the continuation of Jewish settlement building in the West Bank and East Jerusalem.
