Ukraine's military said it struck the Ryazan refinery in Russia overnight.

After late‑August talks collapsed and the U.S. imposed 50% tariffs on hundreds of Canadian goods, Canada announced equivalent reciprocal countermeasures. A poll published Aug. 5 found about 85% support the government's rejection of U.S. terms, 12.2% oppose; roughly 80% back retaliatory measures — the highest on record — and 74% say they do not regard the U.S. as a trustworthy ally.

Israeli sources on the 5th said the Israel Defense Forces are preparing a partial withdrawal from southern Lebanon and plan to establish a smaller "security zone" closer to the Israel–Lebanon border. The move follows a recent operation that destroyed Hezbollah tunnels beneath the Arita-hir highlands in the southern nebetiyeh area; under the proposal the IDF would reduce the depth of its control in southern Lebanon from about 10 km to roughly 3–4 km and replace the existing "yellow line" with a new "grey line." The plan requires Israeli government approval and envisages new military bases inside the reduced zone to protect northern Israeli population centers and stage operations from there.
