The claim that Pope Leo XIV condemned Trump's war effort with Iran is supported by multiple web search results (Claims 1 & 2), but the evidence provided does not allow for a definitive count of *independent* sources confirming this specific condemnation as a standalone fact, only that the criticism exists. However, since the evidence strongly points to this topic being covered across multiple search results, 'single_source' is too weak. Given the strength of corroboration across multiple search results regarding the *topic* of condemnation, 'corroborated' is more appropriate, but since the prompt requires 2+ *independent* sources for 'corroborated' and the evidence is derived from web searches rather than a clear cross-reference count, I will assign 'single_source' based on the lack of clear, distinct source citation for the *entire* claim, while noting the strong evidence.
