The invention of Semtex - a podcast by BBC World Service

In 1958, Stanislav Brebera invented Semtex.

It was a malleable, odourless and stable plastic explosive which became the choice weapon for those seeking to spread terror.

In 2018, Maria Jestafjeva spoke to Mirisov Brebera, the brother of the chemist who created it.
