The Israeli military says, it has reopened a key border crossing with the Gaza Strip after destroying a tunnel built under it by the Hamas militant group. <br/><br/>Today's opening restores Gaza's main point of entry of humanitarian aid. Israel temporarily closed the Kerem Shalom border crossing after it demolished the 1.5-km long tunnel that ran past Israeli military posts as well as gas and fuel pipelines. <br/><br/>Israeli jets struck part of the tunnel and a new set of sophisticated tools destroyed the rest. It is the third such tunnel Israel has destroyed over the past two months.
