The Israeli military says its aircraft have begun targeting militant sites in Gaza in retaliation for a flurry of rockets fired from the blockaded enclave into southern Israel.

The flare-up began Friday when Gaza militants wounded two Israeli soldiers moderately and lightly, respectively. Israeli retaliatory airstrikes killed two Hamas militants. Another two Palestinians were killed during weekly border protests.
