Russian opposition leader Alexei Navalny was rushed to hospital in Siberia after being taken ill on a flight to Moscow. His aides allege he was poisoned in revenge for his campaigns against corruption. The 44-year-old ex-lawyer apparently only drank black tea before taking off from Omsk airport, which his team think was laced with a toxin that put him in a coma.

In 2018, Russian-Canadian activist Pyotr Verzilov was reported to be in a critical condition after allegedly being poisoned in Moscow. It happened shortly after he gave a TV interview criticizing Russia's legal system. Verzilov, the unofficial spokesman for the rock group Pussy Riot, was transferred to a hospital in Berlin where doctors said it was "highly probable" that he had been poisoned.

Sergei Skripal, a 66-year-old former Russian spy, was found unconscious on a bench outside a shopping center in the British city of Salisbury after he was exposed to what was later revealed to be the nerve agent Novichok. Russian President Vladimir Putin’s spokesman Dmitry Peskov called the situation "tragic" but said, "We don't have information about what could be the cause" of the incident.

The estranged half-brother of Kim Jong Un was killed on February 13, 2018 at Kuala Lumpur airport after two women allegedly smeared the chemical nerve agent VX on his face. In February, a Malaysian court heard that Kim Jong Nam had been carrying a dozen vials of antidote for the deadly nerve agent VX in his backpack at the time of the poisoning.

Former Russian spy Litvinenko had worked for the Federal Security Service (FSB) before he defected to Britain, where he became a journalist and wrote two books of accusations against the FSB and Putin. He became ill after meeting with two former KGB officers and died on November 23, 2006. A government inquiry found he was killed by radioactive polonium-210 which it alleged the men put in his tea.

In November 2010, doctors at Berlin's Charité hospital discovered high levels of mercury had been found in a Russian dissident couple working in Berlin. Kalashnikov, a freelance journalist and former KGB colonel, had 3.7 micrograms of mercury per litre of blood, while his wife had 56 micrograms. A safe level is 1-3 micrograms. Viktor reportedly told German magazine Focus that "Moscow poisoned us."

Ukrainian opposition leader Yushchenko became sick in September 2004 and was diagnosed with acute pancreatis caused by a viral infection and chemical substances. The illness resulted in facial disfigurement, with pockmarks, bloating and jaundice. Doctors said the changes to his face were from chloracne, which is a result of dioxin poisoning. Yushchenko claimed government agents poisoned him.

On September 25, 1997, Israel's intelligence agency attempted to assassinate Hamas leader Meshaal, under orders from Prime Minister Benjamin Netanyahu. Two agents sprayed a poisonous substance into Meshaal's ear as he walked into the Hamas offices in Amman, Jordan. The assassination attempt was unsuccessful and not long afterward the two Israeli agents were captured.

In 1978, Bulgarian dissident Markov was waiting at a bus stop after a shift at the BBC when he felt a sharp jab in his thigh. He turned to see a man picking up an umbrella. A small bump appeared where he felt the jab and four days later he died. An autopsy found he'd been killed by a small pellet containing a 0.2-milligram dose of ricin. Many believe the poisoned dart was fired from the umbrella.

On December 30, 1916, mystic and spiritual healer Rasputin arrived at Yusupov Palace in St Petersburg at the invitation Prince Felix Yusupov. There, Prince Yusupov offered Rasputin cakes laced with potassium cyanide but he just kept eating them. Yusupov then gave him wine in a cyanide-laced wine glasses, but still Rasputin continued to drink. With the poison failing, Rasputin was shot and killed.

In August 2017, the UN Security Council adopted a resolution banning all coal, iron, iron ore and lead imports from North Korea. Pictured here is China's Liaoning Greenland Energy Coal Co. in Dandong, on the border with North Korea.

North Korea is prohibited from opening banks abroad, and UN member states are prohibited from operating financial institutions on Pyongyang's behalf. Any dealings that might help North Korea skirt the sanctions are banned, and UN member states must expel and repatriate anyone working on the regime's financial behalf.

This North Korean cargo ship found itself boarded for inspection in the Philippines in March 2016 after the United Nations ordered member nations to de-register any vessel owned, operated or crewed on orders from Pyongyang. North Korean ships also cannot fly the flags of other nations to evade sanctions.

Air Koryo, North Korea's national carrier, remains exempt from aviation sanctions and still has scheduled flights to China and Russia, as well as several domestic routes. However, the airline cannot fly to the European Union, which has banned it on safety grounds, and the United States prevents citizens from legally conducting business with the carrier.

In December 2017, a new raft of UN sanctions targeted fuel imports in North Korea, meaning its residents could have difficulties driving the country in Pyeonghwa sedans (pictured above). The sale and transfer of diesel and kerosene are limited while the import of crude oil is capped at 4 million barrels a year.

UN sanctions limit North Korea's diplomats abroad — at the country's Berlin embassy, for example — to only one bank account each. North Korea is also not permitted to own real estate abroad for any purposes other than consular.

It's a safe bet that North Korea's marching military did not learn its moves abroad: UN sanctions ban foreign security forces from training the country's army, police or paramilitary units. The United Nations does permit medical exchanges, but otherwise allow very little assistance of scientific or technical value.

Anyone wanting to own a larger-than-life Kim will have to await the end of North Korea's nuclear program. The UN sanctions currently ban the sale of statues by the nation.
