Authorities in Indian-administered Kashmir have demolished the houses of at least 10 alleged militants and detained more people for questioning as investigations continue into last week's killings of 26 people.

A day after the U.N. appealed for restraint following Tuesday's deadly attack in Indian-administered Kashmir, India reported an exchange of fire across the de facto border in the disputed region.

In the days since, tensions have risen dangerously between India and Pakistan, which have fought two of their three wars over Kashmir.
