KABUL, Afghanistan (CNN) -- Qatar-based news network Al-Jazeera expressed concern Monday about two of its producers, saying Afghan intelligence officials are holding them in the capital, Kabul.
"Both were detained on Sunday, and we have been unable to make contact since then," according to a statement from Al Anstey, news director for Al-Jazeera English.
Anstey identified the men as Qais Azimy, a senior producer for Al-Jazeera English, and Hamedullah Shah, producer for Al-Jazeera Arabic.
"Al-Jazeera is officially requesting information from the Afghan authorities and is calling for Qais' and Hamedullah's immediate release," Anstey said.
It is unclear why the men were detained. However, the incident happened just days after Azimy filed an exclusive report about the Taliban's takeover of Kunduz province.
The two men were called by Afghan intelligence officials on Sunday and asked to meet at the intelligence department's media center for a "chat," said Al-Jazeera's English office in Kabul.
The two men took a bureau vehicle to the intelligence department, where they were escorted inside, the office said. The driver waited four hours before leaving.
Azimy has a wife and two young daughters in Kabul who are awaiting any information on his detainment, according to the office.
