HIGHLY SECURE: Amid extraordinary security, President Bush arrived in Islamabad Friday on the latest stop of his South Asia tour.

CONTINUING CONCERN: The security precautions underscored the continuing terrorist threat in this poor, conservative Muslim country where a U.S. diplomat was killed in a bomb attack a day earlier.

TRIP GOALS: Bush said he plans to discuss democratic reforms, the war on terror and fostering economic development with Pakistani President Pervez Musharraf.
