An unknown group in Iraq says it has abducted two Egyptian engineers.

In an unauthenticated Internet statement, the Nationalist Movement to Free Iraq says the hostages are being interrogated about why they are in the country. In an accompanying video, two men are shown holding identification cards showing them to work for an Iraqi company.

Meanwhile, an Iraqi-born Swedish citizen who had been held captive since January, says his kidnappers let him go Friday without a ransom being paid.

The Iraqi Vengeance Brigade had threatened to behead Minas al-Yousifi, the head of the Iraqi Christian Democratic party unless a large ransom was paid and U.S. troops withdrew from Iraq.
