The authorities in Pakistan say they have arrested seven foreigners near the Afghan border on suspicion of links to militant groups.
The four men and three women were held after a raid in Charsadda district near the north-western city of Peshawar.
Their names and nationalities have not been released. Officials say they posed as Afghans but knew little Pashto.
Earlier this month, Libyan al-Qaeda suspect, Abu Faraj al-Libbi, was captured in north-western Pakistan.
The authorities say they carried out the latest raid after receiving information that some people of "Middle Eastern origin" were living in Charsadda district.
Pakistan, a key ally in the US-led war on terror, has deployed about 70,000 troops to the Afghan border region in its operation against suspected al-Qaeda and Taleban militants.
Around 600 al-Qaeda suspects have so far been rounded up. Islamabad believes hundreds of militants, including Arabs, Afghans and Central Asians, are hiding in the area.
The arrest of Abu Faraj al-Libbi was the most significant since Khalid Sheikh Mohammed, the alleged mastermind of 9/11, in 2003.
Libbi was wanted in connection with attempts on the life of Pakistan's president.
At the time of his arrest, he was described as the number three in al-Qaeda although some security analysts have cast doubt on his importance.
Since his capture he has been held and questioned at a secret location.
