In an unusual step that indicated Hamas was attempting to prevent further escalation, the Hamas Interior Ministry said the rocket fire went "against the national consensus" and promised to take action against the perpetuators.
Immediately after the IDF confirmation, Prime Minister Benjamin Netanyahu announced he would convene the security cabinet in the military headquarters in Tel Aviv.
The IDF confirmed that two rockets were fired from the Gaza Strip toward Israel on Thuraday, triggering rocket sirens throughout central Israel.
Islamic Jihad, an Iranian-backed militant group that also has a large rocket arsenal, also denied firing the rockets.
"Hamas violently suppresses its own people demonstrating against Hamas' rule & failures today and NOW fires rockets at cities in Israel".
According to media reports, both United Nations and Egyptian officials were seeking to prevent a violent escalation.
Earlier this week, Israel struck Hamas targets in Gaza in response to rocket fire on southern Israel, near the border. "The alert and warning systems operated as required", the IDF said.
Hamas's so-called military wing, the Izz ad-Din al-Qassam Brigades, not only denied it was behind the rocket launchings but said the attacks on Israel came while Hamas members were meeting with Egyptian officials over the Gaza truce. "It's time to defeat Hamas, it's time to demilitarize the Gaza Strip", he said. "No interceptions were made by aerial defense systems".
Sirens were set off, but there were no immediate reports of damage or casualties.
Israel and Hamas are bitter enemies and have fought three wars since the Islamic militant group seized power in Gaza in 2007. "There are no special instructions for the civilian home front".
The Israeli Army strikes in Gaza on Thursday night after Rockets target Tel Aviv, the Israeli military reported, according to Haaretz and Aljazeera. On Friday missiles were seen across the Tel Aviv skyline.
It was the first such attack on the city since the 2014 Gaza war between Hamas and Israel. "There were reports of a number of Israelis who were treated for shock", reports The Jerusalem Post.
Tel Aviv mayor Ron Huldai told the television one of the Gaza rockets "apparently fell into the sea, the other hit somewhere but not in Tel Aviv". He is a New York Times bestselling author and hosts the popular weekend talk radio program, "Aaron Klein Investigative Radio".
