Israeli warships struck several targets in Gaza in response to Thursday's deadly Kassam rocket attack.
Aircraft fired on several tunnels that run under the Gaza-Egypt border near the town of Rafah.
They also hit a metal workshop in Gaza City.
An al Qaeda-linked terrorist group claimed responsibility for firing a rocket from Gaza on Thursday that killed a farm worker from Thailand. They said the attack was for Israel's "judaization" of Muslim holy places in Jerusalem.
"This is the third rocket attack that has directly targeted an Israeli community in the past 24 hours," Israel Police spokesman Micky Rosenfeld said of Thursday's incident.
Yair Farjun, chairman of the Ashkelon Coast Regional Council, urged the international community to "wake up."
"All of these incidents are happening not because Israel is building in Jerusalem, or because a synagogue was opened in the Old City in Jerusalem, they are happening because the Palestinians want all Jews out of this land and seek the destruction of Israel," Farjun told the Jerusalem Post.
"It's time for the world to know the truth," he said. "Those who want to see reality should come here."
