GAZA CITY (CNN) -- An Israeli air strike east of Gaza City early Wednesday killed a militant, Palestinian security and medical sources and the Israel Defense Forces said.
The IDF said the strike targeted armed men approaching the fence in northern Gaza. Palestinian sources said the dead man was a Hamas militant.
Palestinian sources also said that the Izzedine al-Qassam Brigade, Hamas' military wing, was firing rockets at the Israeli border.
On Tuesday, Israeli attacks launched at what Israel said were Palestinians involved in firing missiles into Israel from Gaza killed as many as four people, including two children, Palestinian sources said.
There were conflicting reports about how many people were killed in the initial attack, an air strike. In the second attack, Hamas security sources said Israeli forces had killed two children.
In the first attack, Islamic Jihad said three of its members were killed in an Israeli air strike as they prepared to fire rockets into Israel.
The Israel Defense Forces said an Israeli aircraft fired a missile at two armed Palestinians in central Gaza. An IDF spokesman said the two were about 600 meters from the security fence, making their way toward it.
Palestinian medical sources could confirm only one death and two injured.
In the second attack, the Israeli army said it launched an attack on two Palestinian militants standing near a rocket launcher in northern Gaza, in an area from which a Qassam rocket was fired onto Israel just a short while before.
Hamas security sources said the Israelis hit and killed two children, both age 11, with what seemed to be a ground-to-ground missile.
An Israel Defense Forces representative did not specify what weapons were used. The IDF did not immediately respond to the Hamas accusation that it had killed two children.
On Monday, six members of the Hamas Executive Force were killed in an Israeli air strike in Gaza, hospital and Hamas officials said.
The IDF said that its air force targeted and hit a vehicle carrying Palestinian militants who earlier in the day fired rockets into Israel.
The IDF said during the past four days, more than 40 rockets and mortar shells were fired on Israel from Gaza.
Despite the continued strife in Gaza, the European Union said Tuesday it had reached agreement with the Palestinian Authority for the EU to resume Wednesday -- on a provisional basis -- deliveries of fuel to the Gaza power plant.
Those deliveries were cut off after Hamas seized control of Gaza in June. E-mail to a friend
