Pakistan warned U.S. troops not to intrude on its territory Friday, after the two anti-terror allies traded fire along the volatile border with Afghanistan.
Thursday's five-minute clash adds to already heightened tensions at a time the United States is stepping up cross-border operations in a region known as a haven for Taliban and al-Qaida militants.The clash — the first serious exchange with Pakistani forces acknowledged by the U.S. — follows a string of other alleged border incidents and incursions that have angered many in Islamabad.
Speaking in New York, Pakistan's president tried to downplay the incident, saying only "flares" were fired at foreign helicopters that he said strayed into his country from Afghanistan.
