Two armed Palestinian teens planning to carry out a terror attack in Jerusalem were arrested Monday near the security barrier on the outskirts of the southeastern Jerusalem neighborhood of Har Homa, police said. The two youths, 16- and 17-year-old members of the Hamas youth movement, were apprehended after a security team spotted them near the fence and gave chase. During the pursuit the two suspects hurled a firebomb at the security men, who fired in the air to stop them, Jerusalem police spokesman Shmuel Ben-Ruby said. There were no injuries reported during the late-morning incident. Police subsequently found two firebombs, two knives, a Hamas flag in their possession as well as material for two pipe bombs. The two Palestinians, residents of Dehaishe refugee camp near the West Bank city of Bethlehem, told police investigators that they planned to attack a border police patrol in the area in revenge for the imprisonment of a brother of one of the suspects for security-related offenses, the police said.
