Russian and Syrian warplanes halted their airstrikes on Syria's besieged city of Aleppo on Tuesday in preparation for a temporary pause in the military push that Moscow has announced for later in the week, the Russian defense minister said. According to Defense Minister Sergei Shoigu, the halt in the strikes should help pave way for militants to leave the eastern rebel-held parts of the contested city. Both Russian and Syrian air raids on the northern city of Aleppo were suspended at 10 a.m. Tuesday, Shoigu said. He described the suspension as a precursor for the opening of humanitarian corridors. Moscow on Monday announced a "humanitarian pause" between 8 a.m. and 4 p.m. Thursday to allow civilians and militants safe passage out of the city.
