Israeli warplanes bombed several targets across the Gaza Strip early Monday, injuring four Palestinians. Aircraft fired missiles at an area near the smuggling tunnels in Rafah in south Gaza, leaving a 10-year old child moderately injured, health officials said. Another child and his parents sustained moderate wounds as a result of shrapnel from an Israeli missile which landed near their house in Al-Mughraqa, (Ma'an) news agency quoted health ministry spokesman Ashraf al-Qidra as saying. They were evacuated to Al-Aqsa Martyrs Hospital in Deir al-Balah. The military training site of the Hamas' military wing al-Qassam Brigades in Gaza City's Tuffah neighborhood was also hit, causing a huge fire in the area, but no injuries have been reported. Other airstrikes were reported in an open area near the American School in Beit Lahiya in the northern Gaza Strip, and Nuseirat refugee camp in central Gaza. The Israeli army said they "targeted a weapon manufacturing facility, a terror activity site and a terror tunnel in the northern Gaza Strip as well as a smuggling tunnel in the southern Gaza Strip. Direct hits were confirmed." "The sites were targeted in direct response to the ongoing rocket fire aimed at southern Israel," the Israeli army said added. A rocket fired from the Gaza Strip on Sunday hit a house in Netivot, causing substantial damage, but no casualties. Israel's army said 15 rockets from Gaza have landed in Israel this month.
