The Kremlin has said it is expecting to host 29 world leaders for the May 9th parade.

Moscow Mayor Sergei Sobyanin announced that the newest attack involved at least 19 drones being intercepted while they were inbound to Moscow "from different directions." The assault, coming the day after several drones halted air traffic at a major Moscow international airport, resulted in no destruction or casualties.

The overnight Tuesday attack disrupted even more flight traffic, resulting in stoppages of all flights at four airports in the Russian capital and nine others further outside the city.

In total some 105 Ukrainian drones were intercepted across Russia overnight, according to Russia's defense ministry. Despite these attacks, the Kremlin says that President Putin's May 8-10 ceasefire is still on the table.

"There will be no hostilities. However, if there is no reciprocity from the Kiev regime and they continue to attack our positions or facilities, we will retaliate," Putin spokesman Dmitry Peskov told reporters.

It's a sensitive moment given the major military parade through Red Square will be attended by various heads of state, including China's Xi Jinping. Obviously safety of the skies is paramount, also as planes bring foreign officials into Russia.

The Kremlin earlier this week accused Ukraine's President Zelensky of threatening Victory Day Events. At least one European leader who is expected in attendance has agreed with this assessment:

Slovak Prime Minister Robert Fico confirmed he will attend Russia's 80th anniversary Victory Day celebrations in Moscow on May 9, describing Zelensky's warnings about security risks as "ridiculous," the Magyar Nemzet newspaper reported.

Earlier this week, Zelensky asked foreign leaders to avoid the Victory Day parade in Moscow on May 9, citing security risks. However, Fico stated that threats from Kyiv would not deter him from attending the ceremony. "As a sovereign country, I will not allow anyone to tell me where I can travel," he said, calling Zelensky's threats "an intimidation campaign."

"In my opinion, this is ridiculous. I reject such threats," Fico said at a press conference on Sunday, reiterating that he will be in Moscow for Victory Day.
