"Do not believe in fake information," Ukranian President Volodymyr Zelensky posted on social media after the sun came up in Kiev on Saturday morning. "I am here. We will be defending our country, because our strength is in our truth."

"We will be defending our country," he added.

Zelensky's post comes after loud explosions and intense gunfights broke out in Kiev overnight as Russian troops reportedly entered the capital, Fox News reported.

"A new day on the diplomatic frontline began with a conversation with @EmmanuelMacron," Zelenskyy added in a Twitter post. "Weapons and equipment from our partners are on the way to Ukraine. The anti-war coalition is working!"
