The Israeli military announced early on Friday that it had launched airstrikes targeting positions affiliated to the Palestinian Islamic Jihad resistance group.
Gaza's Health Ministry reported that two injured citizens were being treated following the strike, Presstv Reported.
The strikes threaten to unravel a fragile ceasefire which put an end to two days of fighting after Israel assassinated a senior Islamic Jihad commander in Gaza on Tuesday.
As a result of ensuing fighting, at least 34 Palestinians, including eight children and three women, were killed while another 110 were also injured.
Various Palestinian resistance groups, notably Islamic Jihad, responded by firing reportedly more than 400 rockets into Israel, paralyzing Tel Aviv and other vast parts of the country, leading to the closure of business and roads.
On Wednesday, Hamas officials warned that it would join Islamic Jihad in repelling Israeli aggression if Tel Aviv failed to submit to a ceasefire.
“If airstrikes and aggression continue, Hamas and the resistance groups will have to morally respond to and protect the Palestinian people,” an unnamed Hamas official told the US-based Fox News channel.
Hours later on Thursday morning, Islamic Jihad announced that Israel had accepted its proposed ceasefire conditions, agreeing to halt targeted assassinations and attacks on Palestinian protesters in the Gaza strip in talks mediated by Egypt.
Israeli and Egyptian officials also confirmed the ceasefire.
Shortly later, however, Israeli Foreign Minister Israel Katz, rejected any change in Israeli policy against Gaza while speaking to Israel's Army Radio.
Targeted killings "will not cease", he said, adding that Israel's "open-fire policy" regarding protests at the Gaza border will not change.
Family massacred, Palestinians urge response
Israeli strikes on Gaza killed eight members of the same family, five of whom were children, shortly before Israel submitted to a ceasefire on Thursday morning.
Israel's military claimed that the strike targeted the father of the family, Rasmi Abu Malhous, for allegedly being affiliated with Islamic Jihad.
Relatives, neighbors and an Islamic Jihad spokesman, however, denied that Malhous belonged to the resistance group.
"This is a war crime," said neighbor Adan Abu Abdallah. "You are killing innocent children, sleeping at home," he added.
In another incident, a six-month pregnant woman, identified as Iman Abu Tayyim, suffered a miscarriage in a severe anxiety attack after Israeli bombs landed near her home east of Khan Younis in southern Gaza, according to Palestinian sources.
The recent Israeli strikes on Gaza have greatly angered the local population.
On Friday night, Palestinian sources reported that crowds converged in Gaza's northern Jabalia camp urging for further retaliation against Israel's onslaught.
At least two separate volleys of rockets were reportedly fired into Israel on Thursday. Islamic Jihad has not claimed responsibility for the attacks as a variety of smaller resistance groups also posses rocket arsenals in Gaza.
Israeli officials acknowledged that Islamic Jihad has sought to prevent smaller groups from launching rocket attacks following the ceasefire.
Israel, however, proceeded with the new Friday airstrikes on alleged Islamic Jihad positions, regardless.
