Israeli aircraft killed two Palestinians of the Hamas group that rules the Gaza Strip in a strike Monday, Hamas and Palestinian doctors said. The Israeli army spokesman confirmed the attack, saying the gunmen were located in the area of Bureij refugee camp not far from the Gaza-Israel border. A third Hamas gunman was seriously injured in the attack, Hamas was quoted as saying by the Associated Press. The gunmen were members of a night guard that patrols the border, Hamas said. The force is meant to thwart Israeli troop incursions into the Gaza Strip.
