Here’s all we know about the explosive drone incident at Leipzig airport:

It was first reported early on Wednesday that German police had been called in to investigate a suspicious object found near a runway at the airport after an ‘overnight security incident’ halted traffic.

The southern runway was closed while specialists examined the object using explosives-disposal technology, a police spokesperson said.

Germany’s Bild newspaper reported that the drone had been found lying in the immediate vicinity of a Ukrainian Antonov cargo plane.

Wes Streeting has urged allies to boost Ukraine’s air defences ahead of a winter that Vladimir Putin will seek to use as a “weapon” against Kyiv.

The defence secretary visited Ukraine last week to discuss preparations for the winter, a season where in previous years Moscow has targeted the country’s energy infrastructure in a bid to freeze it into submission.

Writing in the Sunday Times, Mr Streeting said: “Winter in Ukraine is no longer a season. It is a weapon.”

Arguing that while Putin was currently losing the war, now in its fifth year, he warned that “Ukrainians know what winter brings, and how it can change the picture”.

He said: “I return from Kyiv with a clear understanding of what Ukraine needs to weather this winter.

“Where the UK can provide that resource, we will. And where we cannot, it is my job to mobilise allies to find that capability.”

Ukraine paid tribute on Saturday to Oleksiy Yukov, a volunteer who spent more than two decades recovering bodies of civilians and soldiers — many of them Russian — killed by war.

An Orthodox Christian service was held at the Cathedral of Saint Volodymyr, in central Kyiv, where thousands of people gathered to pay their respects following his death in a landmine explosion during a recovery mission on Wednesday.

Mourners also gathered at Kyiv’s main Maidan Square, many dropping to their knees as a sign of respect as his casket was brought to the site. Memorial services were also held in other cities.

Yukov, 40, founded the organisation known as Platsdarm, or Bridgehead, because he believed that all the dead deserve a proper burial. He became known as a “collector of souls.”

Kyiv launched another drone strike on a Wildberries warehouse yesterday in Yekaterinburg, Russia, marking the 20th such attack since 18 July as part of a three-week campaign to ‘bring the war home’ to ordinary Russians.

The latest incident involved three drones hitting the roof of the logistics centre, though the company reported the resulting blaze was contained and most goods remained undamaged.

Satellite imagery from Reuters indicates that these Ukrainian attacks have collectively destroyed one-fifth of the Russian online retailer Wildberries’ total storage capacity.

Odesa has been badly damaged after a night of mass Russian strikes, as Ukraine was hit by over 200 missiles and drones, the country’s officials reported.

Volodymyr Zelensky said on Sunday that eight people had been wounded in Odesa following overnight attacks.

According to the General Staff of the Armed Forces of Ukraine, around 219 missiles and drones attacked the country last night.

Among them were seven ballistic, anti-ship and anti-radar missiles and 202 Shahed drones. Air defences shot down 174 drones and five cruise missiles.

Volodymyr Zelensky says that North Korea is preparing to send 30-50,000 troops to be deployed in allied Russian territory.

Speaking to Ukraine’s United News, he says Pyongyang is “studying” the conflict between Russia and Ukraine, and hoping to “gain experience in modern warfare under Russia”.

He said: “We have already found North Korean missiles on the territory of Ukraine. Today, this is already an established fact.”

Russia continued ⁠strikes on Ukrainian port infrastructure and vessels supporting the Ukrainian military, Russia’s defence ministry ⁠said on ​Saturday.

The ministry said Russian forces used precision air-launched weapons and attack drones to hit military warehouses containing communications and electronic warfare equipment in the Black Sea port of Odesa.

In ‌the port of Mykolaiv, Russian forces struck a cargo vessel ⁠carrying military equipment and a warehouse storing weapons and military supplies, the ministry said.

It added that another dry cargo vessel transporting ‌military supplies for Ukraine’s ​armed forces was ‌hit in the ⁠Black Sea.

Turkish foreign minister Hakan Fidan said that Ankara had conveyed to Russia ⁠and Ukraine ​they ⁠should declare a moratorium ⁠on their ​attacks ⁠in Black Sea.

Speaking ‌to the state-run Anadolu news ‌agency, Fidan ‌said Turkey had conveyed its concerns ⁠about attacks on vessels in the Black Sea to both countries and was ‌implementing certain ​security measures of ‌its ⁠own, but did ⁠not elaborate ‌further.

A drone entered Bulgarian airspace and exploded close to an international gas pipeline shortly after crossing the border from Romania.

There were no casualties or damage.

The defence ministry in Sofia, Bulgaria’s capital, later said there were indications the drone was the kind used by Ukrainian armed forces and that the incident was likely accidental.

Bulgaria and Romania are both members of Nato and the European Union.

A Ukrainian foreign ministry spokesperson said the Ukrainian military was looking into the incident but that it did not deliberately target Bulgaria.

Heorhii Tykhyi said on Saturday that Ukraine and Bulgaria were in “close contact” to establish the circumstances of the incident.

Bulgaria’s prime minister Rumen Radev said the drone exploded just after 5am about 100 metres (109 yards) inside Bulgarian territory.

It was not detected or identified while flying through either Romanian or Bulgarian airspace.
