The wife of Jumpei Yasuda, a freelance journalist who went missing in Syria three years ago and is believed to be held captive by local militants, said Tuesday she hopes for further action by the government to rescue her husband, following the recent release of a hostage video believed to show Yasuda.

At a news conference on Tuesday, where she appeared in public for the first time since his disappearance, his wife, a singer who goes by the name Myu, said that she was "grateful for all of the help provided by the government so far," and also expressed "her deepest apologies to the public for the trouble" that had been caused by her husband's captivity.

The singer repeatedly said how much she appreciated the government's help in trying to rescue her husband, but added that "the Japanese government holds the key to the situation." She also said she believed that the government would take action and had high hopes.
