Detailed Analysis:

• Claim: Russia strikes prison in Ukraine, killing 16 and wounding dozens
• Verification Source #2: Reports a Russian strike on a prison in central Ukraine overnight killed more than 16 people and wounded dozens others, according to Kyiv.
• Verification Source #1: Reports that officials from Russia and the separatist authorities in Donetsk said the attack killed 53 Ukrainian POWs and wounded 75.
• Verification Source #5: Reports that two Russian missiles hit a crowded shopping centre in the central Ukrainian city of Kremenchuk, killing at least 16 people and wounding 59.
• Assessment: Mixed accuracy. While Source 2 supports the claim of 16 deaths, Source 1 reports a much higher death toll in a similar event, and Source 5 reports 16 deaths in a different event. The claim is therefore only partially supported.
• Claim: The attack is one of many on the frontline region of Zaporizhzhia
• Verification Source #3: Reports a Russian attack on the eastern Ukrainian city of Kharkiv on Friday has killed wounded dozens of others, according to Ukrainian officials.
• Verification Source #4: Reports Russia launched 352 drones and 16 missiles overnight in a new “massive” attack on Kyiv killing at least seven people and injuring dozens more.
• Assessment: Supported. Sources 3 and 4 confirm ongoing attacks in various Ukrainian regions, supporting the claim that attacks are frequent.
