Waves of explosives-laden suicide drones have struck Ukraine’s capital, setting buildings on fire and tearing a hole in one of them.

People rushed for shelter or tried to shoot down the kamikazes on Monday.

The concentrated use of the drones is the second barrage in as many weeks — after months where air attacks had become become a rarity in central Kyiv.

The assault sowed terror and frayed nerves as blasts rocked the city.

Energy facilities were hit.

One drone largely collapsed a residential building, killing four people, authorities said.

Intense, sustained bursts of gunfire rang out as the Iranian-made Shahed drones buzzed overhead, apparently from soldiers trying to destroy them.

Others headed for shelter, nervously scanning the skies.

Previous Russian airstrikes on Kyiv were mostly with missiles.

Analysts believe the slower-moving Shahed drones can be programmed to accurately hit certain targets using GPS unless the system fails.

But Ukraine has become grimly accustomed to attacks nearly eight months into the Russian invasion and city life resumed as rescuers picked through debris.

Previous Russian airstrikes on Kyiv were mostly with missiles.

Mayor Vitali Klitschko said Monday’s barrage came in successive waves of 28 drones — in what many fear could become a more common mode of attack as Russia seeks to avoid depleting its stockpiles of long-range precision missiles.

Five drones plunged into Kyiv itself, said Prime Minister Denys Shmyhal.

In the Kyiv region, at least 13 were shot down, all flying in from the south, said Yurii Ihnat, a spokesman for Ukraine’s air force.

One strike appeared to target the city’s heating network, hitting an operations centre.

Another slammed into a four-storey residential building, ripping open a gaping hole and collapsing at least three apartments on top of each other.

Four bodies were recovered, including those of a woman who was six months pregnant and her husband, Mr Klitschko said.

An older woman and another man were also killed there.

An Associated Press photographer caught one of the drones on camera, its triangle-shaped wing and pointed warhead clearly visible against the blue sky.

“The whole night, and the whole morning, the enemy terrorises the civilian population,” Ukrainian President Volodymyr Zelensky said in a social media post.

“Kamikaze drones and missiles are attacking all of Ukraine.”

He wrote: “The enemy can attack our cities, but it won’t be able to break us.”

In a televised address to the nation on Monday night, Mr Zelensky said Moscow is resorting to the drones because it is losing the war.

“Russia doesn’t have any chance on the battlefield and it tries to compensate for its military defeats with terror,” he said. “Why this terror? To put pressure on us, on Europe, on the entire world.”

Andrii Yermak, head of the presidential office, posted on social media that Shahed drones were used.

Mr Zelensky, citing Ukrainian intelligence services, has previously alleged Russia has ordered 2,400 of the drones from Iran.

Russia has rebranded them as Geran-2 drones — meaning geranium in Russian.

A photograph of debris from one of Monday’s strikes, posted by Mr Klitschko, showed the word Geran-2 marked on a mangled tail fin.

Iran has previously denied providing Russia with weapons, although its Revolutionary Guard chief has boasted about providing arms to the world’s top powers without elaborating.

The drones pack an explosive charge and can linger over targets before nosediving into them.

Their blasts jolted people awake.

Snizhana Kutrakova, 42, who lives close to one of the strikes, said: “I’m full of rage. Full of rage and hate.”

The Russian military said it used “long-range air and sea-based high-precision weapons” to strike Ukrainian military and energy facilities.

They hit “all assigned targets”, Defence Ministry spokesman Igor Konashenkov said.

Ukrainian foreign minister Dmytro Kuleba called for European Union sanctions on Iran for providing drones to Russia.

He reiterated Ukraine’s need for air defences and ammunition, saying he had addressed a meeting of EU counterparts from a bomb shelter because air raid sirens were howling.

The European Union’s top diplomat says the bloc is gathering evidence about Iran’s alleged sale of drones to Russia and will respond if the allegations prove true.

EU foreign policy chief Josep Borrell said on Monday: “We are following very closely this use of drones. We are gathering evidence and we will be ready to react with the tools at our disposal.”

The 27-nation bloc on Monday approved a military training programme in Europe for thousands of Ukrainian troops and plans for around 500 million euros (£429 million) in extra funds to help buy weapons for Ukraine.

Iranian-made drones have been used elsewhere in Ukraine in recent weeks against urban centres and infrastructure, including power stations.

At just £17,500 apiece, the Shahed is only a fraction of the cost of higher-tech missiles and conventional aircraft.

The Kalibr cruise missile that Russia has used widely in Ukraine costs the Russian military about £880,000 each.

Drone swarms also challenge Ukrainian air defences.

Western nations have promised systems that can shoot down drones but much of that weaponry has yet to arrive in Ukraine and, in some cases, may be months away.

“The challenges are serious because the air defence forces and means are the same as they were at the beginning of the war,” said Mr Ihnat, the air force spokesman.

Some air defence weaponry supplied by the West can only be used during daylight hours when targets are visible, he added.

Russia forces also hit energy infrastructure elsewhere on Monday, apparently seeking to compound pressure on Kyiv’s government after previous attacks knocked out power supplies.

Mr Shmyhal, the prime minister, said hundreds of settlements were without power after missile attacks on critical infrastructure in the Dnipropetrovsk and Sumy regions.

Ukraine’s nuclear operator said Russian shelling cut off power again to the Zaporizhzhia nuclear power plant, one of the most worrying flashpoints of the Russian invasion.

The nuclear plant, Europe’s largest, needs power for critical safety systems.

When shelling severs its power supply lines, the plant is forced to fall back on diesel generators – a temporary stopgap.

Russian President Vladimir Putin had said on Friday there was no need for more widespread attacks against Ukraine — after a barrage of strikes earlier in the week that he said were retaliation for the bombing of a bridge connecting Ukraine’s Russian-occupied Crimean Peninsula with Russia.

However, Mr Putin also said seven of 29 targets designated after the bridge attack were not hit “the way the Defence Ministry had planned” so Moscow’s forces would continue to target them.

He did not specify the targets.

After months during which strikes in central Kyiv were rare, last week’s attacks put the country and its capital back on edge.

Monday’s strike on Kyiv came amid intensified fighting in the eastern regions of Donetsk and Luhansk, as well as a continued Ukrainian counter-offensive in the south near Kherson and Zaporizhzhia.

Mr Zelensky said on Sunday there was heavy fighting around the cities of Bakhmut and Soledar in the Donetsk region.

The Donetsk and Luhansk regions make up the industrial east known as the Donbas and were two of four regions annexed by Russia in September in defiance of international law.

In the south, Ukrainian air forces reported shooting down nine drones over the Mykolaiv region and six more over the Odesa region.

The governor of the eastern Kharkiv region said overnight attacks on a city and villages killed one woman and hurt four more people.

Russia and Ukraine also completed a prisoner swap on Monday, according to the Russian Defence Ministry.

It said 110 Russians who were freed included 72 seamen from commercial vessels held since February, while 108 female Ukrainian prisoners of war were handed over to Kyiv authorities, with two saying they wanted to stay in Russia.

The Ukrainian side confirmed the exchange but not that two Ukrainians decided to stay in Russia.
