Washington: The US has warned its citizens against all non-essential travel to Pakistan given that the country continues to experience significant terrorist violence including sectarian attacks.

"Pakistan continues to experience significant terrorist violence, including sectarian attacks. Several foreign and indigenous terrorist groups continue to pose a danger to the US citizens throughout the country," the State Department said yesterday in a latest travel warning on Pakistan which replaces that of the one issue on August 28 last year.

While the US Embassy in Islamabad and its Consulate in Karachi continue to provide consular services for all its citizens, the two diplomatic posts are often limited in the services they can provide due to the security environment.

The Peshawar Consulate no longer offers consular services, and the one in Lahore remains temporarily suspended.

Noting that sectarian violence remains a serious threat countrywide and the Pakistan government continues to enforce blasphemy laws, the State Department said religious minority communities have been victims of targeted killings and accusations of blasphemy.

Observing that attacks include armed assaults against heavily guarded facilities, such as military installations and airports, the State Department said terrorists have also struck universities, schools, rallies, places of worship, and large marketplaces in several Pakistani cities.

Since the beginning of 2016, a suicide bomber killed at least 15 people and injured 25 others outside a health centre in Quetta, Balochistan; gunmen attacked Bacha Khan University in Charsadda, Khyber

Pakhtunkhwa Province, killing 22 people; and a suicide bomber at a park in Lahore killed more than 70 people and injured more than 340.

The Pakistan government maintains heightened security measures, particularly in major cities, following attacks or in response to threats, the State Department said.
