Jerusalem: Israeli aircraft hit a disused airport in southern Gaza, injuring 11 people, two of them seriously, Palestinian medical officials and witnesses said.
Four missiles hit the site last night, the witnesses said.
The injured were all in the vicinity of the airport, near the town of Rafah.
The facility itself has long been closed.
An Israeli military statement described the target as "a terror site" and said pilots confirmed that it was hit. It was the second night of Israeli raids since a rocket fired from the Gaza Strip killed a worker on an Israeli farm on Thursday.
Another rocket was fired into Israel earlier on Friday.
The cross-border exchanges came as UN Secretary-General Ban Ki-moon was headed for a weekend visit to Gaza, the West Bank and Israel and as the United States sought to get Palestinians and Israelis talking peace.
