Sept 18 (Reuters) - Some Afghan girls returned to primary schools with gender-segregated classes on Saturday, but older girls faced an anxious wait with no clarity over if and when they would be able to resume their studies at the secondary school level. Most schools in the capital Kabul have stayed shut since the Taliban captured the city just over a month ago. Taliban officials say they will not return to the fundamentalist policies - including a ban on girls receiving an education - when they last ruled Afghanistan from 1996 to 2001. They have now promised that girls will be able to study - but only in segregated classrooms. Nazife, a teacher at a private school in Kabul which had mixed classrooms before the Taliban takeover, said they had made changes in order to reopen. "Girls study in the morning and boys in the afternoon," she said. "Male teachers teach boys and female teachers teach girls."

On Friday the education ministry said boys" secondary schools would soon reopen, but made no mention of girls. "Their spirits are down and they are waiting for government announcements so they can resume studying," said Hadis Rezaei, who teaches the school"s female secondary-level pupils. Taliban spokesman Zabihullah Mujahid told the local Bakhtar News Agency on Saturday that arrangements were being made to reopen girls" secondary schools but he gave no date. "The education of girls is fixing a generation. The education of boys may affect a family but the education of girls affects society," said the school"s principal, Mohammadreza. "We are very closely following the matter so that girls can resume their education and complete their studies."
