Suspected heatstroke kills three lions at Japan zoo

Three lions at a Tokyo Zoo have died from suspected heatstroke and others are under treatment, a spokeswoman said on Tuesday.

Ten of the 16 lions in Tama Zoological Park have suffered symptoms such as "loss of appetite and decreased activity" since mid-July, and three lionesses died. Japan sweltered through its hottest summer on record last year and parts of the country have hit 40 degree C in recent weeks while thousands of people were hospitalized.
