The death toll from last Friday’s attack on Taverna du Liban, a Lebanese restaurant popular among expatriates in Kabul, has reached 21. The murdered foreigners include an American academic, the Lebanese head of the IMF’s Kabul office, two Canadian auditors and the restaurant’s owner, Kamal Hamade. The rest of the victims are unnamed ‘Afghan nationals’, many of them undoubtedly the cheerful young members of staff who would bring out extra dishes at no charge, who smiled when they mispronounced English words and waited to see if I would correct them, who were underpaid but happy at least to have a job. They were shot dead by two gunmen who got in after a suicide bomber destroyed the front gate and main security barrier.
