loudspeaker

South Korea's military says it has suspended its loudspeaker propaganda broadcasts across the border to North Korea, as part of a bid to "restore trust" between both countries.

The streets in Jerusalem leading up to the Knesset, Israel's parliament, were a sea of blue and white Israeli flags, and the noise from vast loudspeakers set up along the route was deafening.

Department of Homeland Security police officers had asked protesters to keep vehicle paths clear earlier in the morning, but their commands over a loudspeaker were often drowned out by protesters’ chants.

The loudspeakers are one tool used by the South Korean government, but behind the scenes a more sophisticated underground movement has flourished.

Every few minutes, the chatter would be momentarily quietened by a voice hissing over the loudspeaker: "Silenzio."
