Three killed in Kabul 'suicide attack' say police
At least three people have been killed in what police say was a suicide attack in the Afghan capital Kabul.
Reports said the blast occurred near a hotel and shopping centre in the city centre. Officials said the dead included security guards.
Exchanges of gunfire were heard following the explosion.
It is the second attack in less than three weeks in the heavily fortified Afghan capital, after nine died in an attack on a supermarket on 28 January.
