Four Gaza resistance fighters were killed overnight in a firefight with the Israeli army after the occupation troops penetrated into the Gaza strip

Four Gaza resistance fighters were killed overnight in a firefight with the Israeli army after the occupation troops penetrated into the Gaza strip, officials said on Friday.
  
The local commanders of Hamas's military wing were martyred by tank fire, Palestinian officials said, while the Israeli occupation army said five of its soldiers were wounded by an explosive device.
  
Palestinian officials said Rabieh Barikeh was killed instantly in the firefight late Thursday night and Khaled Abu Bakr died of his wounds during the night. The bodies of Mohammed al-Qassas and Mohammed Daoud were discovered later. They said all were local commanders of Hamas's Ezzedine al-Qassam military wing.
  
The Israeli military said the fighting erupted when an explosive device went off as troops were clearing a tunnel from the Gaza Strip into the Zionist entity, allegedly to be used as a springboard for resistance attacks.
  
During the operation, Hamas targeted the Israeli occupation soldiers with an explosive device, wounding five of them, it claimed in a statement. In response, "the soldiers opened fire and directly hit a terrorist" and Israeli warplanes struck "an additional terror tunnel located in the southern Gaza Strip," it said.

During the exchange, Hamas TV said, three mortar shells were fired from Gaza into the southern occupied territories. The Israeli army reported only one, which it said fell in an open field, causing no injury or damage.
