BAGHDAD, Iraq — The Iraqi government pledged yesterday it would do everything in its power to protect voters from insurgent attacks during next Sunday's national-assembly election.

Interior Minister Falah al-Naqib said Baghdad's international airport would be closed for three days starting Saturday night; civilians would be forbidden to carry weapons; an 8 p.m. to 6 a.m. curfew would be placed on Baghdad and other cities; and most cars would be banned from streets and travel between provinces would be banned.

Al-Naqib said all leaves and passes for police and military forces have been canceled and that further measures would be announced closer to election day. "We have mobilized all our forces as a government," he said.
