Four smuggling tunnels and a weapons depot in Gaza have been attacked by Israeli military.
According to the military, the strikes on Friday were a response to rocket fire from Gaza at southern Israel, the Associated Press reported.
Earlier Friday, Gaza militants fired two rockets however no damage or injuries were caused.
The latest cross-border exchange came just days before Israel's general election Tuesday in which hardline leader Benjamin Netanyahu is favored to win.
Attacks from both sides has not really come to a complete halt with sporadic rocket fire and airstrikes being fired while the indirect negotiations between Israel and Gaza's Hamas rulers on the terms of a cease-fire are going on.
Both sides have different demands; Israel wants guarantees that weapons smuggling into Gaza will be halted while Hamas seeks an end to a 20-month border blockade of Gaza by Israel and Egypt.
