Some of the 46 Indian Nurses, held hostage by Islamic militants in Iraq, wait at the airport before flying home, on July 4, 2014, in the city of Arbil in the autonomous Kurdistan region of northern Iraq.

New Delhi : Dozens of Indian nurses stranded in territory held by Islamic extremists in Iraq returned home to southern India on Saturday aboard a special flight, officials said.

The 46 nurses had been holed up for more than a week in Tikrit, where fighters of the Islamic State group have taken over. The nurses had been moved to a new area under the extremist group’s control, and finally crossed over late Friday into Irbil, in Iraq’s largely autonomous Kurdish region.

After a brief refueling stop in Mumbai, the plane landed in Kochi, in Kerala state, where the nurses are from.

Another 76 Indians were also aboard the plane that flew them from Irbil, according to Syed Akbaruddin, a spokesman for India’s foreign ministry.

Akbaruddin tweeted that after dropping off the nurses, the plane would transport the others to the southern city of Hyderabad.

It remained unclear whether the nurses had been held by the militants or were just stranded in their territory. The Indian foreign ministry gave no details of how their freedom was secured.

According to the foreign ministry, 39 Indian construction workers abducted two weeks ago were still being held by the militants, but were safe and unharmed.

Speaking to reporters on Friday, Akbaruddin said that any details about the backroom diplomatic maneuvers that India undertook to free the nurses would compromise the safety of the construction workers.

About 10,000 Indians work and live in Iraq, but only about 100 are in violent, insecure areas.

The abducted construction workers were mostly from northern India and had been employed by the Tariq Noor al-Huda construction company.
