Letter bomb

A letter bomb[a] is an explosive device sent via the postal service, and designed with the intention to injure or kill the recipient when opened.

One of, if not the first, groups to consistently use letter bombs on a wide scale were the British suffragettes of the Women's Social and Political Union in the years before the First World War.

[2] The group were the original inventors of a form of letter bomb designed to maim or kill politicians or opponents.

[2] In 1913, numerous letter bombs were sent to politicians such as the Chancellor David Lloyd George and Prime Minister H.H.

[3] Suffragettes also once attempted to assassinate a judge they considered to be anti-women's suffrage, Sir Henry Curtis-Bennett, with a "deadly" letter-bomb made partly out of bullets, but the bomb was intercepted by London postal workers before it could reach him.
