Israeli airstrikes in the Gaza Strip killed three Palestinians and wounded two television cameramen, Palestinian officials and residents said. They said Israeli sniper fire killed a fourth Palestinian and critically wounded a 6-year-old boy on Sunday. The first airstrike Sunday, in the early hours, hit an armored car belonging to the Reuters news agency, wounding five people, including the two cameramen, Palestinian witnesses and hospital officials said. The Israeli army said that in the darkness, no press markings were seen on the vehicle. A Hamas fugitive was killed in another air raid, hospital officials said. The army later reported another strike against a group of Palestinians carrying an anti-tank missile. Hamas said one of its men was killed in that attack. Another Palestinian was killed late Sunday in a similar strike aimed at suspects carrying a missile near the Israeli border, residents said. On Sunday afternoon, a 20-year-old Palestinian man was shot in the head by a sniper in the Shajaiyeh neighborhood of Gaza City, hospital officials said. The army said the man approached troops while he was carrying an anti-tank missile. A 6-year-old boy was shot in the chest and critically wounded in the same area later Sunday outside his home, Palestinian medical officials said. The army was investigating the report.
