START YOUR RESPONSE DIRECTLY WITH THE TABLE. NO INTRODUCTION OR PREAMBLE.

CRITICAL: All information MUST be from real, verifiable sources. DO NOT invent or fabricate any news, events, or details. Only report what you find from actual news sources.

OUTPUT FORMAT: Begin immediately with a markdown table using this exact structure:

| SOURCES | DATE | HEADLINE | CATEGORY | WHAT HAPPENED | ANALYSIS | IMPACT |
|---------|------|----------|----------|---------------|----------|--------|
| [Citation numbers] | [YYYY-MM-DD] | [Descriptive headline] | [War/Security/Economy/Disaster/Politics/Tech] | [3 sentences max from actual sources] | [Why it matters + What happens next + Historical context] | [1-10 score] | [Status] |`;
