Israel launched fresh air strikes on the Gaza Strip overnight after killing two people in earlier raids, the Palestinian health ministry said Saturday, June 23.

According to AFP, the latest strikes targeted two camps of the armed wing of Hamas, the Ezzedine al-Qassam Brigades, in central and northern Gaza, and a former Hamas security post in Gaza City. They wounded about 20 people.

An Israeli army statement early Saturday confirming the latest operations said they were in response to rocket fire earlier in the week into southern Israel.

Israel held Hamas responsible for "all terrorist activity coming from the Gaza Strip," the army statement added.

On Friday, medics in the Gaza Strip reported that two Palestinians had been killed and four wounded when Israeli warplanes struck twice.

A first Israeli air strike on Friday afternoon targeted the east of Al-Bureij in the central part of the Gaza Strip, killing Basel Ahmad, 29, who was of no known affiliation, local medical sources said.

Two other Palestinians were wounded in the strike, one of them seriously, the sources added. Israeli aircraft "targeted a terrorist squad during preparations to fire a rocket at Israel from the central Gaza Strip. A hit was identified," the military said in a statement.

A second Israel air strike killed another Palestinian in the north of Gaza. Two other Palestinians were slightly injured in the same attack.

Earlier on Friday, Palestinian militants in Gaza fired two rockets that hit southern Israel, without causing casualties or damage.

The violence came despite a tenuous Egyptian-brokered truce between Israel and Gaza's Hamas rulers. It was announced late Wednesday by the Islamists' Ezzedine al-Qassam Brigades military wing after a flurry of deadly exchanges in and around the territory.
