Pakistan capital put on high alert

Pakistan has heightened security in Islamabad amid threats from the country's Taliban that it will takes its fight to the capital.Security threats prompted schools to shut down and embassies to restrict movement of their staff on Friday.Nematullah Kundi, a Pakistani police official, said: "This is a high alert. We have stepped up security in the city, in and around the diplomatic enclave and the area near the parliament building, which is the declared red zone."Extra guards have also been deployed at schools in the red zone and elsewhere in the city."While much of the recent violence has been concentrated in northwest Pakistan, where the army has been fighting pro-Taliban fighters, many fear Islamabad could be next.
