Islamabad: The US embassy in Pakistan's capital suspended consular services on Friday due to "heightened security", an official said.
However, the US consulates in Lahore, Karachi and Peshawar will be open on Friday, the Dawn quoted a spokesman as saying.
The spokesman said while regular consular services, such as visa processing for Pakistani nationals, won't be available in the capital on Friday, the embassy will provide emergency services to Americans.
Islamabad has witnessed violence in recent weeks, including a suicide bombing near a major road that killed eight security personnel.
The embassy staff must be vigilant while travelling to public places, restaurants and hotels due to serious security threats posed to US citizens, Geo TV reported, quoting a statement issued by the embassy.
Security has been beefed up at key places in Islamabad and offices of some multinational companies were closed on Friday.
Private schools here were closed for the day in a bid to avoid any untoward incident, the report said.
Intelligence agencies have warned of a possible suicide attack in the Pakistan capital as dozens of terrorists have entered key cities, another media report said.
