UCDP's words. Source: UCDP Candidate Events Dataset Codebook, version 1.5 (Introduction) and UCDP GED Codebook, version 26.1 (section 2, the definition of an event), copied on 2 Oct 2026.

This page rests on UCDP GED 26.1 and UCDP Candidate Events 26.0.9, with data through 30 Sep 2026. The figures from January 2026 are from Candidate Events. Candidate Events are preliminary and UCDP revises them.

The pages give counts and their sources. They give no travel, security or safety advice. A count of events is not a measure of danger.

Each chart has its own scale. The page of each country has the figures as a table.

Figure 1. Events in Iran by month. A hollow column is a preliminary month. The line marks the change of dataset: GED to the left, Candidate Events from Jan 2026 to the right. The two datasets are not made in the same way, so a step at the line is not only a change in the events.

Figure 2. Events in Yemen by month. A hollow column is a preliminary month. The line marks the change of dataset: GED to the left, Candidate Events from Jan 2026 to the right. The two datasets are not made in the same way, so a step at the line is not only a change in the events.
