Israeli military says it struck militant targets in the Gaza Strip overnight in response to rocket fire on Tel Aviv.
In response to the launches, the IDF said in a statement that it struck some 100 targets throughout the coastal enclave.
In Gaza, health officials reported that four people were wounded, including a husband and wife in the southern town of Rafah.
No militant groups have said they fired the rockets at Tel Aviv.
Israel's military has confirmed it was attacking so-called "terror sites" in Gaza. Shortly afterwards, the Israeli air force launched a series of strikes targeting Hamas naval bases in Gaza. The assessment indicated that Hamas had no intention of escalating violence with Israel.
Israel strikes Gaza after two rockets fired at Tel Aviv
The Iran-backed Al-Sabareen terrorist group in Gaza has yet to release an official statement following the rocket attacks.
"In keeping with the public interest, the commission has made a decision to exceptionally postpone its activities scheduled for this day", the body which organizes the protests said in a statement, according to AFP. "Hamas is in complete control of the situation and understands how to deal with it", said the source, adding that Hamas might initiate a confrontation with Israel in order to divert the attention of the general population if the protests spread.
The army said early Friday that targets included an office complex in Gaza City, an underground complex that served as Hamas' main rocket-manufacturing site, and a center used for a Hamas drone program.
Harsh sirens rang out across the streets as citizens were warned of the first missile attacks since 2014. Israel and Egypt have maintained a crippling blockade on Gaza since Hamas took over the territory in 2007.
Palestinian factions have criticized the crackdown on the protesters in Gaza, stressing their right to peaceful protest and to express their views on their dismal situation under Hamas rule.
Hamas' violent clash with protestors suggests residents have little desire for another war with Israel.
Naftali Bennett, a member of Netanyahu's security Cabinet who is vying against him for rightist votes in the looming election, demanded the assassination of Hamas chiefs. More than 2,100 Palestinians were killed in Gaza during that war, a lot of them civilians, along with 66 Israeli soldiers and seven civilians in Israel.More news: UEFA Champions League Quarter-Final Draw Revealed
