SRINAGAR, Kashmir — Fears of communal violence were once again raised in the disputed region of Jammu and Kashmir on Thursday when a grenade blew up at a crowded bus stand, killing one person and wounding many others.

Around the same time, videos of two Indian men beating Kashmiri street vendors in a northern Indian city went viral online, further stoking tensions.

The violence followed a week of hostilities in Kashmir between India and Pakistan, both of which claim the mountainous region.
