Pictures of political leaders have been ordered to be removed even from websites, they said.
"All public hoardings carrying images of party leaders, government schemes or any political references have been ordered to be removed or covered up in accordance with the model code of conduct," Delhi's Chief Electoral Officer Ranbir Singh said.
Another senior official said use of any imagery of armed forces or invoking references to air strike on posters, hoardings or any other publicity platform "would amount to violation of the poll code of conduct".
