AGRA, India Thousands of security personnel took up positions Friday in the Taj Mahal town of Agra for a final drill against possible terrorist attacks during the Indo-Pakistan Summit at the weekend.

Roadblocks as far as 60 kilometers (32 miles) from the city were being manned to search vehicles for any firearms being smuggled into Agra, which enjoys a dubious reputation as one of India's most crime-prone regions.

Prime Minister Atal Behari Vajpayee will reach Agra late on Saturday night, while Pakistani ruler Pervez Musharraf will arrive a few hours later on Sunday for the first summit between the two nations since February 1999.

The two leaders will check into separate hotels in Agra's highest security area where the police said no one will be allowed without valid identification.

"We will hand over the two hotels tomorrow to security agencies," Agra Police Chief A.K.D. Diwedi told AFP, as anti-terrorism experts began a final drill against bomb attacks aimed at derailing the historic summit.

Pan-Islamic groups such as the Lashkar-e-Taiba have opposed the upcoming meeting between Vajpayee and the Pakistani military ruler.

"We are keeping a close watch on all suspicious characters, but we have not detained anyone so far," the police chief said, adding the department was being helped by several federal security agencies now camping in Agra.

Sources said Agra police had already carried out the painstaking task of a house-to-house search for "strangers" in the run up to the India-Pakistan Summit.

The 17th-century Taj Mahal will remain closed to visitors on Saturday and reopen Tuesday, Kumar said.

For the first time in many years the enclosures containing the graves of Moghul Emperor Shah Jahan, who built the Taj Mahal, and his wife Mumtaj Mahal will be opened for Musharraf and his wife.
