The Palestinian National Authority (PNA) condemned on Wednesday the killing of an Israeli soldier at an Israeli army roadblock south of northern West Bank city of Nablus.

PNA Prime Minister Salam Fayyad said in a press statement sent to reporters that PNA condemns the attack, stressing that PNA would keep carrying out its firm security measures in order not to repeat such incidents.

"Our people are united towards the peaceful resistance of settlement activities and the construction of the separation wall, as well as against the behavior of settlers. Such a peaceful manner is getting a worldwide support," said Fayyad.

He warned in the statement of "the dangers of being dragged to violent actions which would bring damage to the national interests of our people." Fayyad called on the Palestinians to be aware of such violent actions.

Israeli Radio reported earlier on Wednesday that 33-year-old Palestinian police officer Mahmoud al-Khatib, from the West Bank city of Jenin, was arrested after he stabbed an Israeli soldier to death.

The radio reported that al-Khatib attacked the soldier who was driving a car near an Israeli roadblock south of Nablus, and stabbed him by a knife in his chest. The Israeli died shortly after he was stabbed and al-Khatib was detained.

The radio added that al-Khatib tried to escape from the scene, but another Israeli army car chased him, where he was hit and lightly wounded, and then he was taken to jail.

Meanwhile, Palestinian residents of the town of Ya'bad close to Jenin said that around 25 Israeli army vehicles stormed the town, and broke into al-Khatib's house.

The residents said that Israeli soldiers broke into al-Khatib's house, arrested his brothers and sisters and locked them up into one of the rooms and questioned them about Mahmoud al-Khatib.
