Egyptian army destroyed 6 Gaza tunnels

Cairo - The Egyptian army has destroyed six underground tunnels connecting the Sinai to the Gaza Strip, from Feb. 21 to March 13, according to a statement released by the army on Wednesday.
In 2014, Egypt established a buffer zone along its border with the Hamas-governed Gaza Strip, to prevent it from collaborating with ISIS-affiliated Islamist gangs which have been attacking Egyptian army and police in the Sinai.
In 2015, the Egyptian army began flooding the tunnel network with seawater in an attempt to destroy it.
