A series of loud explosions rocked Ukraine's capital Kyiv early Monday morning, a day after Moscow blamed Ukraine for a deadly blast on the bridge linking Crimea to Russia.

The explosions hit Kyiv around 8:15 a.m. local time (5:15 a.m. GMT), and an Agence France-Presse (AFP) journalist in the city saw numerous ambulances appearing to head toward the scene of the blasts.

"Several explosions in the Shevchenkivskyi district – in the center of the capital," Kyiv Mayor Vitali Klitschko said on social media.

Videos posted on social media showed black smoke rising above several areas in the city.

Ukrainian President Volodymyr Zelenskyy said there were dead and wounded in blasts that rocked cities across Ukraine on Monday and accused Russia of trying to wipe his country "off the face of the earth."

"They are trying to destroy us and wipe us off the face of the earth ... destroy our people who are sleeping at home in (the city of) Zaporizhzhia. Kill people who go to work in Dnipro and Kyiv," Zelenskyy said on the Telegram messaging app.

"The air raid sirens do not subside throughout Ukraine. There are missiles hitting. Unfortunately, there are dead and wounded," he added.

Russia's last strike on Kyiv took place on June 26.

Ukrainian media also reported explosions in a number of other locations, including the western city of Lviv that has been a refuge for many people fleeing the fighting in the east, as well as Kharkiv, Ternopil, Khmelnytskyi, Zhytomyr and Kropyvnytskyi.

Energy infrastructure was damaged in Lviv, according to regional Governor Maksym Kozytskyi.

The explosions came a day after Moscow blamed Ukraine for the explosion on a bridge linking Crimea to Russia, leaving three people dead.

"The authors, perpetrators and sponsors are the Ukrainian secret services," Russian President Vladimir Putin said of Saturday's Crimea bridge bombing, which he described as a "terrorist act."

Putin was speaking during a meeting with the head of the investigation committee he has set up to look into the bombing, Russian news agencies reported.

The Russian leader is gearing up for a meeting with the U.N. Security Council later Monday, the Kremlin told local news agencies.

"Tomorrow the president has a planned meeting with the permanent members of the Security Council," Kremlin spokesperson Dmitry Peskov said.

The blast that hit the bridge sparked celebrations from Ukrainians and others on social media.

But Ukrainian President Volodymyr Zelenskyy, in his nightly address on Saturday, did not directly mention the incident, and officials in Kyiv have made no direct claim of responsibility.

On Saturday, Russia said some road and rail traffic had resumed over the strategic link, a symbol of the Kremlin's 2014 annexation of Crimea.

The 19-kilometer (12-mile) bridge is a vital supply link between Russia and the annexed Crimean peninsula.

Some military analysts argue that the blast could have a major impact if Moscow sees the need to shift already hard-pressed troops to Crimea from other regions – or if it prompts a rush by residents to leave.

Mick Ryan, a retired Australian senior officer now with the Center for Strategic and International Studies in Washington, said that even if Kyiv was not behind the blast, it constituted "a massive influence operation win for Ukraine.

"It is a demonstration to Russians, and the rest of the world, that Russia's military cannot protect any of the provinces it recently annexed," he said on Twitter.

Merciless strikes

Zelenskyy meanwhile denounced a Russian missile strike on Sunday that killed at least 13 people, one of them a child, in Zaporizhzhia – the latest deadly bombardment of the southern Ukrainian city.

The attack also wounded 89 people, including 11 children, according to a statement from the president's office.

Zelenskyy described the "merciless strikes on peaceful people" and residential buildings as "absolute evil" perpetrated by "savages and terrorists."

Regional official Oleksandr Starukh posted pictures of heavily damaged apartment blocks on Telegram and said a rescue operation had been launched to find victims under the rubble.

Russian officials meanwhile denounced on Sunday what they said was a surge in Ukrainian fire into its territory that had hit homes, administrative buildings and a monastery.

Russia's FBS, which is responsible for border security, said on Sunday: "Since the start of October, the number of attacks from Ukrainian armed formations on Russia's border territory has considerably increased."

More than a hundred artillery attacks, concentrated on the western border regions of Belgorod, Bryansk and Kursk, had hit housing and administrative buildings, said the statement.

The attacks had killed one person and wounded five others.

Çavuşoğlu's standpoint

Foreign Minister Mevlüt Çavuşoğlu spoke with his Ukrainian counterpart Dmytro Kuleba by phone on Monday, discussing the latest wave of Russian missile attacks on the capital Kyiv and other major Ukrainian cities.

"I had a call with my Turkish counterpart Mevlüt Çavuşoğlu who strongly condemned Russian strikes and affirmed that Türkiye will continue its support for Ukraine. We coordinated efforts on mobilizing a resolute response within the U.N. General Assembly," Kuleba wrote on Twitter following the call.
