Israeli warplanes have struck and destroyed two tunnels under Gaza's border with Israel. The Israeli military says Gaza militants had planned to use the tunnels to enter Israel and carry out attacks.
No one was hurt in Saturday's raids.
The military says the air strikes came in response to Gaza rocket fire two days earlier on the Israeli border community of Netivot.
The Israel-Gaza border has been relatively quiet in the past year, since the end of Israel's three-week war on Gaza's Hamas rulers, meant to halt Gaza rocket fire.
Despite sporadic cross-border violence, Israel and Hamas are in the advanced stage of indirect negotiations on a prisoner swap. Hamas holds an Israeli soldier and wants Israel to free 1,000 Palestinians.
