Israel is looking for U.S. aid to build a system that can find find and destroy secret Hamas tunnels that breach the Jewish nation's border, Defense News reports. 

News of the funding hunt comes in the wake of the discovery last week of a sophisticated Hamas-built tunnel that snaked beyond a fence protecting Israeli communities.

"The working assumption is there are more," Israel Defense Forces spokesman Lt. Col. Peter Lerner said, Defense News reports.

Israel's Ministry of Defense has invested more than $60 million in anti-tunnel technologies, and is hoping for at least twice that amount from Washington in the coming two years, an unnamed source tells Defense News.

The U.S. aid would let Israel develop supplemental technologies, and move forward with testing and production, the website reports.

In December, Congress included $40 million in its omnibus spending bill for U.S.-Israel anti-tunnel technology development, Defense News reports. Israel is hoping for at least another $40 million in 2017 and in 2018, defense and industry sources in Israel tell the website.
