Dozens of armed militants briefly took control of Palestinian government buildings in the Gaza Strip Saturday to demand jobs.

Witnesses and security sources say members of the Al-Aqsa Martyrs Brigade, an armed wing of the Fatah movement, occupied several offices in central Gaza.

Separately, gunmen protesting the death of a police officer set up a roadblock at Gaza's border crossing with Egypt, threatening to prevent officials from passing. The police officer had been recently killed in a family feud.

Late Friday, gunmen in Gaza released three British hostages who had been seized earlier in the week in Rafah. A previously unknown group, Mujahadeen Brigades Jerusalem Branch, claimed responsibility for the kidnapping.

Also Friday, Palestinian police briefly occupied the Gaza-Egypt border crossing at Rafah to protest the killing of the officer, forcing the crossing to temporarily close.
