(MENAFN- Arab News) SANAA: Rival Shiite and Sunni groups have met for the first time for talks aimed de-escalating the crisis since the former seized Sanaa in September they said Saturday.

The meeting between Ansarullah chief Abdelmalek Al-Houthi and Al-Islah party delegates took place late Thursday in Houthi's northern stronghold of Saada the Shiite militants said on the Internet.

The rivalry has intensified since Ansarullah moved beyond Sanaa and also seized territory in central and western Yemen. The Shiite advance has slowed in the face of a counter-offensive by Sunni tribes close to Al-Islah and Al-Qaeda plunging the country into an unprecedented political crisis.

Al-Islah issued a statement saying the two sides 'expressed willingness to cooperate and coexist in accordance with the precepts of Islam advocating brotherhood love and peace.'

The statement said that because of 'the dangers threatening Yemen it was agreed to continue contacts to end the tension and contain the impact of recent events.'

An Al-Islah official told AFP the two sides were 'negotiating a draft agreement' that according to a source close to the talks was meant to 'defuse the risk of sectarian conflict' in Yemen.

Support for Al-Islah previously a main political force with its tribal alliances has wavered since president Ali Abdullah Saleh quit in early 2012 after a year of bloody protests.
