Russia has already fired 600 missiles since invasion of Ukraine – Pentagon official

Russia has already fired 600 missiles since the invasion of Ukraine.

According to CNN, a senior U.S. defense official said this on Sunday, Ukrinform reports.

The U.S. observed ongoing fighting in Kherson and Mykolaiv on Sunday and Russian forces are still trying to encircle Kyiv, Khakhiv, Chernihiv, and Mariupol, according to the official. But the advances have been met with strong Ukrainian resistance, slowing the Russian assault.

Meanwhile, the massive Russian convoy north of Kyiv that spans some 40 miles of road remains stalled, but there is no update on how far it is from Kyiv. Late last week, it was approximately 16 miles (25 kilometers) from Kyiv's city center.

The skies above Kyiv remain contested, and both Ukrainians and Russians retain a significant majority of their air combat power.

"We believe the Ukrainian people in most parts of the country still have means of communication, access to internet and the media," the official added.

The official also said the U.S. has not observed an amphibious assault near Odesa and they do not assess one is imminent.

The official could not confirm reports of Russians firing on protestors in Kyiv or violations of the ceasefire agreement to allow for humanitarian corridors. The official also could not corroborate reports the Russians are calling up reserves.

As was reported earlier, Russian President Vladimir Putin launched a large-scale invasion of Ukraine on February 24. Russian troops are shelling and destroying infrastructure, conducting massive shelling of residential areas of Ukrainian cities and towns using artillery, multiple launch rocket systems and ballistic missiles.

Martial law was imposed in the country and general mobilization was announced.

Ukraine officially filed a lawsuit against the Russian Federation to the International Court of Justice in The Hague.
