Two Britons have been confirmed dead after a devastating suicide attack which has killed at least 21 people in Kabul.
Wabel Abdallah, the head of the IMF's Afghanistan office, and United Nations civilian staff died in what UN chief Ban Ki-moon said was a "horrific attack".
The Foreign Office (FCO) has also named one of the British nationals killed in the blast as Dhamender Singh Phangurha, but was unable to provide any more details.
Labour leader Ed Miliband has paid tribute to European election candidate Del Singh, saying:"My thoughts - and the thoughts of the whole Labour Party - are with the family and friends of Del Singh who was killed in yesterday's tragic suicide bomb in Kabul.
"People everywhere will be appalled and shocked by this barbarous act of terror deliberately targeting members of the international community living and working in Kabul in the service of the Afghan people.
The blast occurred at the Taverna du Liban restaurant, which is popular with tourists and westerners, in the Afghan capital, officials say.
The attack was carried out at a time when the restaurant would have been busy with diners.
Five women were among the dead at the city's popular Taverna du Liban, and at least five were injured, police say.
The suicide attacker detonated his explosives outside the gate of the heavily-fortified restaurant, the Deputy Interior Minister Mohammad Ayoub Salangi said.
Two gunmen entered the restaurant and started shooting at people inside.
It is believed that attackers were eventually shot dead by security forces when they arrived at the scene.
