Two Reuters television journalists have been missing in Syria since Saturday, when they were expected to return to Lebanon.
Beirut-based producer Ayat Basma and cameraman Ezzat Baltaji were expected to arrive at Lebanon Saturday night to be picked up by a taxi, but they never arrived, Reuters reported.
They were last heard on Saturday night at 5:22 p.m. GMT, when Baltaji sent a phone message to a Beirut colleague saying, "We will leave now."
They traveled to Syria on Thursday to report on the country's unrest after the ongoing protestests, CNN said.
Reuters Editor-in-Chief Stephen Adler said in a Reuters report, "Reuters is deeply concerned about our two Reuters television colleagues who went missing in Syria on Saturday. We have reached out to the relevant authorities in Syria and have asked for their help in securing our colleagues' safe return home."
