President Donald Trump says the US has begun major combat operations against Iran. Airstrikes have been carried out by Israel and the US, with multiple provinces hit. Iran in turn has fired back at Israel and targeted US bases and assets in the region, including Bahrain, the UAE, Kuwait and Iraq. 

This comes after weeks of talks failed to produce a fresh agreement on Iran’s nuclear program. OPEC+ will consider the option of a larger supply increase when key members meet on Sunday.

In Episode 4 of The Sixth Bureau, a series from The Big Take,we follow a spy from China’s Ministry of State Security as he tries to plan a delicate overseas meeting with a valuable source. But the person he’s talking to isn’t working alone.

The Sixth Bureau from Bloomberg News follows an MSS intelligence officer whose mission was to acquire the crown jewels of American aerospace companies. With aliases, blackmail and the occasional break-in, he targeted corporate giants. That is, until his sloppiness — and a cunning FBI sting — led to a stunning reversal: Xu Yanjun became the first Chinese intelligence officer ever convicted on American soil.

The Sixth Bureau is the story of superpowers, their secrets and how one Chinese spy got caught. Listen to Episodes 1 - 3 here.
