How a herd of elephants circle their young to protect them - not from the threat of predators, but when AIR RAID sirens sound at Tel Aviv zoo during Hamas rocket attack

The footage captured yesterday at the Zoological Center in Tel Aviv, shows the animals freely walking around in a pen, when suddenly an alarm starts whirring signaling Palestinian attack. Immediately one of the elephants lets off an aggressive trumpet call which causes the pack to group together. The elders then circle around two tiny calves in a bid to keep them safe from harm.
