Palestinians are using tunnels under the Egyptian-Gaza border to smuggle cows into the Gaza Strip for the upcoming Muslim festival Eid al-Adha.
    
Despite the fact that Israel allows 3,000 tons of humanitarian aid into the Gaza Strip daily, including cows, smugglers say the cows the Jewish state lets through do not meet the necessary festival requirements. 

Palestinian tradition dictates the bovines must at least 2 years old and weigh more than 1,100 pounds.
    
However, it's not cows and other foodstuffs coming through the tunnels that worry Israel.

Palestinians have smuggled tons of high explosives, bomb-making materials, rockets, mortars, anti-tank and anti-aircraft missiles into the Gaza Strip through the tunnels. 
   
Israel has targeted many of those underground weapons passages over the years, only to have many of them rebuilt by the Palestinians. 

"[Islamic] fundamentalism is the problem of the entire Western world, not only Israel's," the mayor of Rome said while touring the area last year.
