Gunmen assassinated three members of the committee of drafting permanent constitution for Iraq on Tuesday.

The victims, all Sunni Arab members, were gunned down in central Baghdad when gunmen opened fire at their car near al-Azaeim restaurant in the capital, Salih al-Mutlak, spokesman of the Sunni National Dialogue Council, told Xinhua.

"Mejbil al-Sheikh Issa, Aziz Ibrahim and Dhamin Hassan al- Ubaidi, who represent the Sunni Arab among others, were killed by gunmen Tuesday afternoon," Mutlak said.

Issa and Ubaidi were nominated by the council for the country's constitutional committee, which brought 15 Sunni members and 10 advisors on board as required by the Sunni community.

Mutlak warned that the Sunni Arabs may withdraw from drafting the constitution after the killing.

"We demand that the government rapidly hunt down the killers, otherwise we may withdraw from drafting the constitution," Mutlak said.

The assassination was the first against the 71-member committee, which is tasked with submitting a draft permanent constitution by Aug. 15.
