Yemen government, Houthis reach agreement to end crisis - source
Houthi protesters have been blocking the main road to Sanaa's airport and holding sit-ins for weeks at ministries in an attempt to oust the government and restore fuel subsidies.
The negotiator told Reuters the agreement was signed by Sanaa's governor, Abdelqader Helal, and Houthi representative Hussein al-Ozzi, who is in charge of political affairs.
