CAIRO (AP).-Egyptian prosecutors questioned the culture minister for three hours over the theft of a Vincent van Gogh painting that has put him on the defensive over the state of museum security around the country. Farouk Hosni said he sought in Sunday night’s session to dispel accusations he failed to respond adequately to calls for increased security at Egyptian museums, including the one from where the van Gogh was stolen. No alarms and only seven of 43 security cameras were working at Cairo’s Mahmoud Khalil Museum when the $50 million painting, known titles of “Poppy Flowers” and “Vase with Flowers,” was stolen in the middle of the day on Aug. 21. Hosni does not face formal accusations
