IDF aircraft struck targets in the Gaza Strip in the early hours on Thursday, Hamas said, a day after Palestinians fired about a dozen rockets and mortars across the border, striking deep into Israel.
Hamas said Israel targeted smuggling tunnels along the Gaza-Egypt border, as well as one of its training camps in central Gaza.
A third strike hit a power transformer, causing blackouts in the area, witnesses said. Medical workers said no one was injured in the strikes.
An Israeli military spokeswoman said she was checking the report. About a dozen rockets and mortars were fired from Gaza into southern Israel, some reaching as far as the city of Beersheva, some 35 km (20 miles) away, the spokeswoman said.
