GAZA CITY (Ma’an) -- Islamic Jihad's military wing published two short videos showing what it said was a new type of rocket launcher firing projectiles toward Israeli targets.
The footage shows three rockets launched toward Israeli tanks, according to the group.
The Al-Quds Brigades says it has fired about 70 rockets and missiles toward Israeli communities in response to Israeli attacks on the people of the Gaza Strip.
Islamic Jihad said it had fired 70 short-range rockets and mortar bombs across the border since Saturday, salvos which drove Israeli residents to blast shelters.
At least one Israeli, in the town of Sderot, was wounded, ambulance workers said.
Earlier a jeep ambush injured four soldiers in what Israeli officials called an attack that was part of a Palestinian strategy of trying to curb its countermeasures against possible cross-border infiltration.
The al-Quds Brigades said it fired 13 rockets towards the city of Ashkelon and the PFLP's Abu Ali Mustafa Brigades said it fired three rockets into the western Negev, while the Al-Mujahideen brigades claimed responsibility for two rockets.
Earlier, the Popular Resistance Committee said it had fired four rockets at communities close to the border and the towns of Sderot and Netivot in southern Israel, in what it called "the revenge invoice" for Israeli tank attacks on Gaza.
"We reaffirm the option of confrontation and resistance to the occupation, and we will continue our resistance and our military responses as long as the occupation continues," the Abu Ali Mustafa Brigades said in a statement.
An Israeli army statement said it too was escalating attacks as aircraft targeted a weapon manufacturing facility, two weapon storage facilities and two rocket launching sites in northern Gaza, as well as a weapon storage facility and a "terror activity site" in southern Gaza.
Direct hits were confirmed, the statement said.
It said 30 rockets had been fired from the Gaza Strip in the previous seven hours.
