The BBC's Yalda Hakim speaks to Afghans trying to cope with the country's food crisis. A foreign ministry spokesman tells her it's not the Taliban's fault. Also in the programme: "Black Tuesday" for the Turkish currency, the lira; and the United States releases 50 million barrels of oil to try to bring down energy prices.
