A 39-year-old Palestinian attacked his manager and a colleague with a hammer on a Modi'in building site on Tuesday afternoon, wounding one seriously and another moderately.
The two injured were taken to Tel Hashomer hospital. According to police, there is a growing suspicion that the attack was nationalistically-motivated.
Workers at the site managed to overpower the attacker, a resident of Beit Sira in the West Bank, who was in Israel on a permit. Police said the suspect, 39, was taken in for questioning.
On Monday, eleven people were wounded in a vehicular attack next to the the Chords Bridge at the entrance to Jerusalem. The attacker was shot dead at the scene.
This is a developing story.
