An explosion near the US consulate in Pakistan's northwestern city of Peshawar has killed at least five people, police say.
Two Americans were among the five killed in Monday's blast, the regional information minister Mian Iftikhar said.
A policeman told the AP news agency that an explosive-filled car struck a US government vehicle after it left the consulate. Seventeen more people were injured.
The blast took place near residential quarters for the US consulate and foreign aid organisations, senior police officer Tahir Ayub told the AFP news agency.
Witnesses said two vehicles were completely destroyed in the explosion. Some of the wounded are foreign nationals, police officer Pervez Khan told the AP. The identities of those killed were unclear.
US officials could not immediately be reached for comment. Al Jazeera's Imtiaz Tyab, reporting from Islamabad, said: "What we are hearing is that three are people dead, and a number of people are wounded after a vehicle slammed into a US consulate vehicle."
According to our correspondent, there is "some suggestion that those who are injured are foreign", but there are "conflicting reports as to who exactly was targeted in this attack".
The area hosts several foreign organisations, including the UN. Peshawar is situated near tribal areas bordering Afghanistan, where Taliban and al-Qaeda operate.
