Reuters is reporting that fifteen militants were killed in the Sinai Peninsula by helicopter rocket fire. The state-run Nile TV reported the incident on Tuesday, but gave no further details. According to witnesses, the army helicopters attacked militant strongholds in two villages south of Sheik Zuweid, a town near the Israeli border and the Hamas-run Gaza Strip.

An army source confirmed a ground operation was under way with air cover, but declined to give any further details because the operation is still ongoing.
