WASHINGTON: The United States remains concerned about India-Pakistan tensions as the two nuclear-armed countries' militaries remain on alert despite some de-escalation in the region, a senior US administration official said on Wednesday.

"We do still see the militaries on alert and so we realize if there, God forbid, would be another terrorist attack, then you could quickly see escalation in the situation once again," the official told reporters on condition of anonymity.

Tensions between India and Pakistan over the Kashmir region, which both claim, make the area one of the world's most dangerous flashpoints.

The simmering dispute erupted into conflict late last month when Indian and Pakistani warplanes engaged in a dogfight over Kashmir on Feb. 27, a day after a raid by Indian jet fighters on what it said was a militant camp in Pakistan. Islamabad denied any militant camp exists in the area, and said the Indian bombs exploded on an empty hillside.
