Residents of Khabarovsk in Russia’s Far East have been staying indoors or wearing masks when they go outside since a thick smog blanketed the city on Tuesday.
Wakazi wa Khabarovsk, mji ulioko Mashariki ya Mbali nchini Urusi, wamekuwa wakikaa ndani au kulazimika kuficha nyuso zao wanapokwenda nje tangu ukungu mzito kuufunika mji wao tangu Jumanne.
