The U.S. television network Fox has identified two of its employees who were kidnapped by Palestinian gunmen in the Gaza Strip Monday.

A Fox spokesman named American correspondent Steve Centanni and cameraman Olaf Wiig from New Zealand. Witnesses say the two were taken away by gunman after their car was intercepted in Gaza City.

Meanwhile, witnesses say an Israeli airstrike in Gaza has destroyed an empty house. The Israeli military said it was targeting a command center of the Islamic Jihad militant group, and had warned residents of the house before the airstrike took place.

Earlier, Palestinian hospital officials said an Israeli military strike in northern Gaza killed three Palestinians, including a teenage boy.

Israel's military says it targeted Palestinian militants in the area after they fired two rockets at the Israeli city of Ashkelon.

Islamic Jihad claimed responsibility for the rocket attack, which did not cause any casualties.
