GAZA STRIP - The Israeli Air Force targeted two weapons smuggling tunnels near the Rafah border crossing with the Gaza Strip and a weapons factory in southern Gaza near Khan Younis.
The air strikes were in retaliation for Wednesday morning's Kassam rocket attacks by Gaza-based Palestinians on western Negev communities.
The rockets landed in open fields in Sha'ar HaNegev Regional Council, with no injuries or property damage reported.
"The attack is in response to rockets fired at Israel on Wednesday morning. The IDF will respond forcefully to any attempt to disrupt the calm in the south," an IDF spokesman said on Thursday.
In the past month, Palestinians in Gaza have fired some 15 rockets and mortar shells on southern Israel.
Hamas officials acknowledged the tunnel hits, but called the weapons-manufacturing plant a "military facility," saying three people were injured in the air strike.
IDF officials say most of the smuggling tunnels targeted during Operation Cast Lead, the three-week military operation in Gaza nearly a year ago, are fully operational again.
