A Qassam was fired from Gaza into Israel late on Tuesday.
There have been others, a few days ago.
UPDATE
The IDF says:
Overnight, an Israeli Air Force (IAF) aircraft targeted a site of terror activity in the northern Gaza Strip, confirming a direct hit. No civilian causalities were reported.
The site was targeted as a response following the recent launch of rockets from the Gaza Strip.
The IDF will not stand by as southern Israeli communities live under the constant threat of rocket attacks. The IDF will continue to respond with determination to attempts at terrorizing Israeli civilians by the Hamas terrorist organization, which is solely responsible for all terrorist activity emanating from the Gaza Strip.
