Aug 6 (Reuters) - Rescuers worked on Thursday to douse fires and clear debris in Ukraine's eastern city of Balakliia after Russian strikes on homes killed three overnight, authorities said on the Telegram messaging app.

Without Patriot interceptors, Ukraine's skies are wide open and people are fully exposed to Russia's missile barrages.

Ukraine officials say three people killed in Kharkiv region and three in Sumy, as Russia says it intercepted 605 drones.

Russia and Ukraine are producing ever larger numbers of innovative aerial weapons, hoping for a breakthrough as ground combat is largely frozen.

Ukraine's military on Thursday struck two Russian oil refineries in long-range drone attacks as Kyiv continues to target energy infrastructure. Zelenskyy said Ukraine's armed forces struck the Bashneft-Novoil refinery in Bashkortostan and the Slavneft ...

The strikes have drawn attention not only because of their reach inside Russia, but also because of Wildberries’ economic importance, its ties to the country’s financial sector, and the impact on ordinary Russian consumers.

The U.S. and its partners depend on Patriot interceptors to shoot down incoming ballistic missiles. But Russia and Iran are firing their weapons at rates far higher than Patriots can be produced.

The targets hit included a brewing company, a warehouse for construction material, and a mail sorting office that had nothing to do with the war, Ukraine’s President Volodymyr Zelenskyy said. But the Russian Defense Ministry said the businesses masked ties to the military.
