The Egyptian army has arrested two Turkish television journalists in the capital, Turkish media reported Tuesday.
Nazli Oztarhan, bureau chief of Turkey's private StarTv channel, said reporter Murat Uslu and cameraman Zafer Karakas were arrested, but the reason for the arrests was not immediately known.
"The Turkish embassy in Cairo has contacted Egypt's foreign ministry and military authorities. We want them to be freed immediately," Oztarhan wrote on Twitter.
The Hurriyet daily said Turkish authorities have appealed for the men's immediate release.
Turkish journalists who witnessed the arrests told the daily that the military seized all of Uslu and Karakas' equipment as well as their passports.
An Egyptian acting as a fixer for the two Turkish men was also briefly arrested before being released.
Turkey Tuesday strongly condemned the killings of at least 51 people by the Egyptian military Monday outside the headquarters of the Republican Guard in Cairo, where deposed president Mohammed Morsi is being kept.
