Israeli security forces have increased their alert status at the nation's airports, seaports and border crossings amid intelligence reports warning of a possible "dirty bomb" attack, Israel's Ynet news portal reported on Sunday.
A dirty bomb is an ordinary explosive device that is laced with radioactive materials, effectively creating a low-grade nuclear weapon that can cause mass casualties by emitting high levels of radiation over a large area. Experts warn that dirty bombs are frighteningly simple to obtain the ingredients for and assemble.
Earlier in the year, the United States implemented similar security measures, fearing that terror groups such as Osama bin Laden's Al Qaeda were working to smuggle dirty bombs or the needed components to make them into the country.
