Seven Palestinians were wounded in a series of Israeli airstrikes on the Gaza Strip early Sunday morning, two days after fire exchanges that left three dead from both sides.

According to emergency medical sources in Gaza, the seven were wounded in four airstrikes, two carried out at targets east of Khan Yunis, in the southern part of the Palestinian territory, and two that hit Beit Layiha in the northern section of the Strip.

The Israeli army confirmed that its planes had carried out attacks, and said they were retribution for a militant attack from Gaza that had resulted in an Israeli fatality.

"Israeli aircraft targeted three weapon manufacturing facilities and the central Gaza Strip, as well as two terror tunnels in the northern and southern Gaza Strip," a statement from the military read.

"Direct hits were confirmed."

"This is in response to the infiltration on Friday morning, in which Staff Sergeant Nitnel Moshiashvilli was killed by terrorist fire adjacent to the security fence," said the statement.

Military sources said that the sites that had been targeted belonged to Hamas, which rules the territory, and the radical Islamic Jihad group.

The Friday morning infiltration was executed by Ahmed Nasser, a member of the Islamic Jihad, who was killed by Israeli soldiers.

An Israeli airstrike later that day at Palestinians on a motorcycle east of Khan Yunis resulted in the death of a member of the Popular Resistance Committees, who according to the army was part of a squad that had fired a rocket at Israeli soldiers.
