The two warring sides in Yemen have begun to exchange prisoners, as part of the UN-brokered ceasefire.
"We have started the exchange in small groups," a member of the Yemen government's prisoner affairs committee told AFP. He added that they are concerned about security issues involved in the exchange.
The government is expected to release 375 Houthis, while the Houthis are expected to free 285 pro-government fighters.
The fighting, which began in March, has claimed the lives of over 5,800 people so far. The UN says that about half of the dead were civilians.
