Palestinian militants fired two rockets into southern Israel late Tuesday, following Israeli airstrikes near the Gaza Strip's border with Egypt.
Israeli military officials say no one was hurt in the rocket attack.
Earlier on Tuesday, Israeli aircraft bombed at least six smuggling tunnels near the southern Gaza town of Rafah.
Israeli military officials say one of the airstrikes triggered a secondary explosion, indicating that explosives were present in the tunnel. At least four people were reported wounded in the strikes.
Israel launched a three-week offensive against the Palestinian militant group Hamas in Gaza in response to the rocket attacks. Both Hamas and Israel declared separate cease-fires last month, but the violence continues almost daily.
Some information for this report was provided by AFP, AP and Reuters.
