The Israeli military says it has discovered another tunnel — the biggest so far — dug from the Hamas-ruled Gaza Strip that stretches into Israel and was intended for attacks on soldiers and civilians.

Spokesman Lt. Col. Peter Lerner said Friday the opening of the "terror tunnel" was found hundreds of meters (yards) inside Israel.

Lerner did not elaborate and the tunnel is currently off limits to media because of concerns it could be booby-trapped.

Hamas spokesman Abu Obeida blamed the tunnel's discovery on recent rains that exposed its opening.

In 2013, Israel found three tunnels, including one that was a mile long. In 2006, Hamas-allied militants sneaked into Israel through a tunnel, killed two Israeli soldiers and kidnapped a third, holding him hostage in Gaza for five years.
