Israeli Prime Minister Benjamin Netanyahu on Monday lashed out at what he saw as the world's "faint" response to an alleged Iranian attempt to ship weapons into the Gaza Strip.

"At most I heard a few faint condemnations of Iran from the international community after we intercepted this murderous shipment," Netanyahu told a news conference at the naval base in the Red Sea resort of Eilat, referring to the weapons seized by Israeli naval forces in a pre-dawn raid last Wednesday.

A group of journalists and foreign military attaches and ambassadors were at the base Monday to view a display of the seized weapons, including 40 long-range M-302 missiles with a range of between 90 km to 160 km, 180 mortar shells and 400,000 rounds for AK-47 assault rifles.

The Israeli military said the powerful M-302, which carries a 150-kg warhead, would have posed threat to millions of Israelis if the shipment had reached Gaza.

In an effort to prove that Iran was behind the shipment of arms, which was concealed under cement sacks in more than 100 containers, the Israeli navy displayed some documents which it said unequivocally point to Tehran.
