Israeli fighter jets targeted an Islamic Jihad base near Khan Yunes, a house in Deir El Balah, and an open space in Rafah.
Palestinian medical sources reported that four people were injured in the air-strike.
Israel Defense Forces (IDF) said that the new attack came as a response to Hamas mortar attack on Israel. They added that in past two days Palestinian terrorists triggered more than 10 mortar rockets and a Grad rocket to Israel.
"The IDF will also continue to respond harshly to any attempt to use terror against the state of Israel," said IDF in a news release.
