Officials in Pakistan say a suspected suicide bomb blast near the home of a politician has killed at least four people.
The bombing happened Thursday in the northwestern town of Charsadda, close to a house belonging to Asfandyar Wali - head of the Awami National Party. Officials say Wali was not hurt in the attack.
In another development, United Nations employees in Pakistan's capital, Islamabad, will no longer be allowed to live with their children in the country due to heightened security measures.
U.N. officials say the secretary general approved raising security following last month's deadly truck bombing in Islamabad.
The attack at a Marriott Hotel left more than 50 people dead, and greatly raised fears about the country's security.
Britain has also issued an order for its diplomats' children to leave Pakistan.
Some information for this report was provided by AFP, AP and Reuters.
