The Kremlin said on Monday that it was following with great concern the tense atmosphere at the India-Pakistan border in Kashmir, where suspected militants killed at least 26 people in attack last week.

India said it attacked nine sites in Pakistan and Pakistani Kashmir early on Wednesday following a deadly attack on its side of the Himalayan territory last month, while Pakistan reported some casualties and said it was responding.

The offensive occurred amid heightened tensions between the nuclear-armed neighbors in the aftermath of an attack on Hindu tourists in Indian Kashmir.
