Success Rate of Israel's Iron Dome Defense System Questioned

Although Israeli officials say 84 percent of rockets from Gaza were intercepted an American missile expert claims the rate of success was much lower

A leading US expert on missile defence has raised doubts about the efficacy of Israel's Iron Dome defence system.

Israeli officials say it hit some 84% of the targets engaged in last year's conflict with Hamas in Gaza.

But Professor Theodore Postol of the Massachusetts Institute of Technology suggests the defence system's success rate may have been "drastically lower".
