A group of nearly 50 Indian nurses have been taken against their will by bus from a hospital in the militant-controlled city of Tikrit in Iraq, India's foreign ministry.
Foreign ministry spokesman Syed Akbaruddin declined to say who had taken the nurses, or where they were headed, but said the government had spoken with them shortly before they boarded the bus.
Asked about reports of an explosion near the hospital, he said was not aware of a blast, but that some nurses had been lightly injured by broken glass.
"In zones of conflict there is no free will," Akbaruddin told reporters at a briefing, when asked if the nurses had been kidnapped. "This is a situation where lives are at stake."
Tikrit, the birthplace of former President Saddam Hussein, has been the site of fierce fighting this week as Iraqi troops battle to regain control of the city from the Islamic State (IS).
A group of 40 construction workers were kidnapped in the northern Iraqi city of Mosul two weeks ago, and all but one of them are still in captivity.

It said the pair "shared their view of Islam as requiring participation in violent jihad against any non-believers," and YM told her he was an active member of ISIS.
