47 in Afghanistan in less than three months. Earlier on Tuesday, bombs killed a top Afghan policeman and four other people, but the government said Taliban guerrillas would not derail parliamentary polls on Sept. 18. Government spokesman Jawed Ludin vowed the parliamentary elections would be held on schedule and would be even more successful than last October's presidential ballot won by U.S.-backed Hamid Karzai. "The (guerrilla) challenges are very feeble," said Ludin. The police chief of Sarkano district in the eastern province of Kunar was killed along with two of his sons when a roadside bomb blew up their vehicle south of the provincial capital Asadabad, officials said. Seven police were wounded. Several rockets landed near a U.N.-Afghan election commission office in Asadabad, but caused no casualties or damage. --More 2238 Local Time 1938 GMT
