Kuleba, who is part of the Ukrainian Foreign Ministry's communications team, cites three deaths in Kharkiv.
A summary from our newsroom of today's events:
The Ukrainian military and pro-Russian rebels have agreed to start pulling back heavy weapons from the front line in eastern Ukraine in accordance with a recent cease-fire agreement.
Petro Kanonik, commander of Ukrainian officers at the Common Coordination Control Center for the Cease-Fire, said the two-week process of arms removal would begin on February 22.
In the rebel-held Donetsk, senior separatist commander Eduard Basurin was quoted as saying that rebels had signed the orders to complete the withdrawal over the next two weeks, starting from February 22.
Under the terms of the truce, mediated by Germany and France and put into effect on February 15, the withdrawal of the weapons was meant to have started on February 17 and be completed by March 3.
But it was delayed due to fighting in the strategic town of Debaltseve, which government troops pulled out of on February 18 and pro-Russian forces quickly occupied, angering Western backers of the cease-fire.
Ukraine and the separatists meanwhile exchanged 191 prisoners late on February 21.
Each side continues to accuse the other of violating the cease-fire.
Kyiv said on February 22 rebels violated the cease-fire a dozen times during the night with artillery and rocket attacks. Military spokesman Andriy Lysenko said one Ukrainian serviceman was killed and three wounded over the past day.
Explosions were heard in Donetsk early on February 22 and a rebel website said several buildings in the city were damaged by artillery.
In the government-controlled eastern city of Kharkiv, an explosion killed at least two people and injured 10 more during a peace march on February 22, authorities said.
The AFP news agency quoted Kharkiv police spokeswoman Natalia Zakharova as describing the blast as an apparent "terrorist" explosion, a term Ukrainian officials use for pro-Russian separatist rebels.
The blast occurred during a demonstration marking the one-year anniversary of the overthrow of the country's former pro-Kremlin president.
Similar peace marches were taking place in Kyiv and other parts of Ukraine on February 22 but not in areas controlled by pro-Russian forces.
Kharkiv is located more than 200 kilometers from the front line.

The International Committee of the Red Cross has issued an urgent appeal for assistance to "people trapped in Debaltseve," in eastern Ukraine, and expressed hopes that the security situation will allow deliveries of aid.
Here's the text of the ICRC's e-mailed message:
This weekend, the International Committee of the Red Cross (ICRC) delivered food, medical supplies and other essential items to the roughly 5,000 people trapped in the town of Debaltseve by heavy fighting over the past week. The struggle for control of this key transportation hub had been going on for several days after the ceasefire that came into force on 15 February.
“We arranged for humanitarian aid to be delivered as soon as the security situation allowed,” said Joan Audierne, head of the ICRC’s office in Donetsk, who led the five-truck ICRC humanitarian convoy that carried much-needed aid to Debaltseve. “The humanitarian situation is dire, and needs are acute and diverse. The shelling has caused an enormous amount of damage and destruction, to public and residential buildings, and to the town’s infrastructure. People have been living in basements for the past few days, and they are coming out only now, after the fighting has ended.”
Food and other essential items, such as blankets, tarpaulin and candles, will enable people in Debaltseve to meet their basic needs for the next two weeks. As the local hospital remains closed, the ICRC, along with other humanitarian organizations, donated medical supplies to the only functioning primary-health-care post in the town. “We remain committed to continuing to address the situation in Debaltseve in the near future,” said Michel Masson, the head of the ICRC’s delegation in Ukraine. “We only hope that the security situation will let us do so.”
Reuters quotes from a Ukrainian regional prosecutor's online statement:
"According to eyewitness accounts the explosive device was thrown from a passing car," the statement said.
There are rumors, including the usually reliable @kevinrothrock, that "suspects" in the Kharkiv bombing have already been detained.
Choice to use the term "our guys" certainly a bizarre one.
