Al-Jazeera has obtained hundreds of confidential "spy cables" from some of the world's top intelligence agencies, in what the news channel is calling "the largest intelligence leak since Snowden."

Documents from Britain's MI6 and Israel's Mossad are included, along with the Russian FSB, South African SSA and the Australian ASIO. (No American intelligence agencies appear to be included.) Al-Jazeera is publishing the leaks over the coming days in conjunction with the Guardian, promising that they will provide "an unprecedented insight into operational dealings of the shadowy and highly politicised realm of global espionage."
