Russia and Ukraine
Abu Dhabi talks end their first day with humanitarian issues in focus
Russia and Ukraine held about four hours of U.S.-mediated talks on Tuesday and are due to meet again today. President Volodymyr Zelenskyy said the session focused largely on prisoner exchanges, civilians in captivity, the return of Ukrainian children and security guarantees. Officials described the discussions positively, but no broad settlement was announced. Humanitarian agreements would offer a concrete test of progress while the larger disputes over territory and security remain.

Fossil CO₂ emissions are projected to dip, while total emissions rise
The Global Carbon Budget projects fossil-fuel CO₂ emissions will fall 0.4% in 2026, helped by clean energy growth and lower oil consumption during the Iran war. The estimate was released as a preprint at COP31. Including land-use change, total CO₂ emissions are projected to rise to 43.3 billion tonnes from 42.8 billion in 2025. The researchers say clean energy is expanding too slowly to secure a lasting decline, and part of the oil reduction could reverse as the energy shock eases.
Middle East
Iran’s security chief says negotiations with Washington are not underway
Mohsen Rezaei, Iran’s top security official, said Tuesday that no negotiations with the U.S. were taking place and that Tehran still awaited a clear response to its conditions. His comments followed President Donald Trump’s meeting with Qatar’s prime minister and remarks playing down a return to major warfare. The positions remain far apart, with Iran linking the reopening of the Strait of Hormuz to U.S. action on its demands.
