The Ukrainian President has said that using US-provided Patriot anti-missile systems ensured a 100% interception rate and would play a role in pushing forward against Russia's invasion.
"When Patriots in the hands of Ukrainians ensure a 100% interception rate of any Russian missile, terror will be defeated," Volodymyr Zelensky said in his nightly video address.
The president said that with military successes "and with our Patriots, we have to continue responding to Russia and all its manifestations of evil".
He described today as "a very long" one, saying "Russia wants to go to the end on the path of evil" with its attacks.
President Zelensky made his remarks after overnight and daytime attacks on Kyiv and other targets by Russian missiles and drones.
Earlier, Russia said its military hit Ukrainian air bases in the strikes and Ukrainian forces shelled industrial facilities inside Russia.
In a rare acknowledgement of damage to a military "target", Ukraine said that work was under way to restore a runway and that five aircraft were taken out of service in the western region of Khmelnitskiy, although it did not name the site or sites.
A large military airfield was located in the region before the war.
"At the moment, work is continuing to contain fires in storage facilities for fuel and lubricants and munitions," the Khmelnitskiy regional governor's office said.
Russian state-owned news agency RIA cited the defence ministry as saying that more than one air base had been hit, but there was no confirmation from Ukraine of damage to any other air bases.
The Ukrainian capital came under attack for the 16th time this month after a second successive night of bombardment.
But officials said most of the drones and missiles fired overnight had been shot down and no targets were hit in the morning.
One man was injured and taken to hospital, they added.
The attacks, which sent Kyiv residents running for shelter in metro stations, were part of a new wave of Russian air strikes this month as Ukraine, armed with new Western weapons, prepares a push to try to take back territory Russia has seized in the "special military operation" which it launched in February 2022.
"With these constant attacks, the enemy seeks to keep the civilian population in deep psychological tension," said Serhiy Popko, the head of the city's military administration.
The general staff of Ukraine's armed forces said in its evening report that all 11 missiles used in the daytime attacks had been destroyed. But it made no mention of the Patriot systems.
Yuriy Ihnat, a spokesperson for Ukraine's air force, suggested the Patriot was behind the latest results against incoming Iskander ballistic missiles.
"I think you can guess," he told Ukrainian television.
"If Iskander-M missiles are intercepted, you can draw conclusions about the means that specifically targeted the objectives - ballistic targets."
Meanwhile, Kyiv's parliament also adopted a sanctions package against Russia's ally Iran, a day after Ukraine said Moscow used Iranian Shahed drones in the largest attack on the capital since the start of the invasion.
Any peace deal should include demilitarised zone - Ukraine
Moscow said it invaded its neighbour to "denazify" the country and protect Russian speakers.
Western opponents dismiss the invasion as an imperialist land grab in which tens of thousands have been killed, millions uprooted and whole cities reduced to ruins.
Russia has repeatedly said it is open to resuming peace talks with Kyiv, which stalled a few months after the invasion, and has welcomed mediation efforts from both Brazil and China.
A Ukrainian presidential aide said that any post-war settlement should include a demilitarised zone of 100-120km inside Russia along the border with Ukraine.
The zone would be necessary to protect Ukrainian regions from shelling, presidential adviser Mykhailo Podolyak wrote on Twitter.
Ukraine's military said an attack on Odesa port had caused a fire and damaged infrastructure but did not specify whether the damage threatened grain exports.
The country is an important global grain supplier and the port is vital for shipping agricultural products abroad. It is also one of three included in a United Nations-brokered deal on the safe export of grain via the Black Sea.
Russia said on Monday the deal would no longer be operational unless a UN agreement with Moscow to overcome obstacles to Russian grain and fertiliser exports was fulfilled.
This month Moscow reluctantly agreed to extend the grain deal until 17 July.
After months of attacks on energy facilities, Russia is now targeting military facilities and supplies to try to disrupt Ukraine's preparations for its counterattack, Kyiv says.
Moscow says Ukraine has stepped up drone and sabotage attacks against targets inside Russia as it prepares for the offensive.
The governor of Russia's Belgorod region, which borders Ukraine, said several frontier settlements were shelled simultaneously by Ukrainian forces today.
Two industrial facilities were hit in the town of Shebekino and four employees were wounded, Vyacheslav Gladkov wrote on Telegram.
Ukraine said it had shot down 29 of 35 drones and 37 of 40 cruise missiles fired overnight by Russia, and the Kyiv military administration said its air defences had shot down more than 40 of the "targets" fired at it.
"Another difficult night for the capital," mayor Vitali Klitschko said on Telegram.
The attack follows one the previous night - the largest drone barrage yet launched on Kyiv - in which one person was killed and several injured.
In yesterday's attack, 36 drones were downed over the city.
The European Union's foreign police head, Josep Borrell, said he believed Russia would only be willing to negotiate if it won the war in Ukraine, adding that he was "not optimistic" about what could happen in the conflict this summer.
"I see Russia's clear intent to win the war," Mr Borrell told an event in Barcelona.
"Russia will not go into a negotiation if it doesn't win the war."
He added that Moscow has repeatedly signaled it would not cease the campaign until its military goals have been achieved.
"I'm afraid that between now and the summer, the war is going to continue. (Russian President Vladimir) Putin has amassed over 300,000 men there, twice as many as he had when he launched the invasion," Mr Borrell told reporters after the event.
Russia's military presence in Ukraine was "enormous" and it was still bombing Ukraine daily and destroying civilian infrastructure, he added.
"I'm afraid that they don't do that without a plan. We have to be prepared, which means continuing to help Ukraine, because if we don't help it, Ukraine cannot defend (itself)," Mr Borrell said.
