Al-Quds Brigades, armed wing of the radical Islamic Jihad, claimed responsibility on Wednesday morning the firing of two rockets at Israel, in a statement released in Gaza.
Al-Quds Brigades have attributed the authorship of two rocket attacks against the town of Beersheba in the Negev (southern Israel) and that of Ashdod, near the border with the Gaza Strip.
"This is an initial response to the Zionist crimes committed against our people in Gaza," the statement said.
These new rockets are part of an escalation of violence since Saturday between armed Palestinian groups in Gaza and Israel.
Eight Palestinians, four civilians including two minors, and four Islamic Jihad fighters were killed by Israeli fire in Gaza on Tuesday, the deadliest day in the Palestinian territory controlled by Hamas for more than two years.
On the night of Wednesday, two Islamic Jihad militants were wounded, one seriously, during an Israeli air strike in the Zeitoun neighborhood in Gaza City.
