Ukraine's sudden flurry of diplomatic activity

STORY: In a flurry of diplomacy on Sunday, Ukraine's President Volodymyr Zelenskiy held talks with the leaders of the U.S., France and Turkey.

With the war now dragging into a tenth month, there appears to be no end in sight to the deadliest conflict in Europe since World War Two.

In his nightly address, Zelenskiy said he was constantly working with partners, adding that he expects some important results next week from a series of international events.

It's rare for Ukraine's president to hold talks with all three leaders in just one day.

During his call with Biden, the U.S. leader promised to help boost Ukraine's air defense to protect the civilian population.

Zelenskiy said his call with French President Emmanuel Macron, earlier in the day, had lasted more than an hour.

The two leaders spoke about "defense, energy, economy, diplomacy."

While Zelenskiy's call with Turkey's President Erdogan focused on making sure Ukraine can export its grain.

In turn, Erdogan's office said the Turkish leader also had a call on Sunday with Russian President Vladimir Putin, in which Erdogan had called for a quick end to the conflict.

Moscow calls its action in Ukraine a "special military operation" designed to disarm its neighbor, while Ukraine and its allies say it's an unprovoked act of aggression.

On the ground in Ukraine, heavy fighting continues with the entire eastern front line continuously being shelled.

Moscow is also targeting Ukraine's energy infrastructure, at times cutting off electricity for millions of civilians.
