In my case the bees (Africanized bees) were really aggressive. Some kids were throwing rocks in their beehive a few seconds before my sister and I passed by (that was in an almost deserted public street).

The bees were really angry and we got stung multiple times. Luckily we’re not allergic and were able to run away. They stopped attacking after we were out of range (my guess), about 70 meters away.

Edit: typo.
