Israeli airstrikes left at least five Palestinians wounded and one missing early Friday in the Gaza Strip, witnesses and officials in the territory said.
The witnesses said that Israeli F-16s struck a smuggling tunnel under the border between southern Gaza and Egypt, where five people wounded, dpa reported.
Rescue teams rushed to the scene and sent three people with moderate wounds and two with minor injuries by ambulance to the nearby Rafah hospital, Gaza emergency chief Adham Abu Selmeyeh said.
Earlier, Israeli F-16s carried out two airstrikes late Thursday against another smuggling tunnel and an empty area inside Gaza.
An Israeli army spokesman had said Thursday that militants from the Gaza Strip fired a fourth homemade projectile at southern Israel.
In the last three days, Israeli forces have carried out six airstrikes, in response to four homemade missiles fired by militants from Gaza toward towns in southern Israel.
In April, Israel and militant groups in Gaza reached a ceasefire agreement through mediators without making any official declaration.
