Israel's military says its aircraft struck infrastructure in Gaza used by the militant group Hamas that rules the coastal territory after gunmen there continued to fire mortars at forces along the border.
Friday's fire comes after three days of violence in which Gaza militants fired mortars, prompting Israeli retaliatory fire. Palestinian attacks intensified after Israel uncovered a tunnel Thursday stretching from Gaza into Israel.
Military spokesman Lt. Col. Peter Lerner said, "The repeated attacks against the IDF activities to locate and destroy cross border tunnels will not be tolerated. Hamas' diabolical plan to infiltrate into Israeli communities must be stopped."
The recent violence has been among some of the most serious violence between Gaza and Israel since 2014. Hamas used tunnels to attack Israel during that 50-day war.
