In a press conference in Stockholm, UN Special Envoy Martin Griffiths said representatives of Yemeni government and Houthi rebels have been negotiating in Stockholm since last week.

Griffiths said humanitarian issues have been prioritized in the negotiations.

Griffiths also reiterated the importance of continued restraint on the ground and called on two parties to respect their obligations under international humanitarian law.
