Negotiations are underway between Saudi Arabia and Yemen's Houthi group to discuss a military truce between the two sides, Al Jazeera sources said.

The sources added that a political and military committee had been formed between the Saudis and the Houthis to discuss measures to stop fighting on the border and stop air strikes.

This comes on the heels of successive indications and initiatives that have shown the desire of both sides to calm down. Saudi Crown Prince Mohammed bin Salman then expressed hope that it would lead to political dialogue.

A source told Al-Jazeera Net earlier that a direct contact was made between Saudi Deputy Defense Minister Khalid bin Salman - brother of Mohammed bin Salman - and the head of the Supreme Political Council of the Houthis, Mehdi Mashat.

He added that the contact took place days after the unilateral truce began in late September, in a statement read by Mashat.

According to the source, who preferred to remain anonymous, Khalid bin Salman offered to form a committee from both sides to reduce the escalation, and to reach a full ceasefire agreement between the parties on the Saudi-Yemeni border.
