The 10 injured were transferred to a military hospital.Monday's suicide attack comes just after Saturday's ambulance bomb attack in Kabul that left 103 dead and more than 200 injured.The ambulance attack came a week after a previous assault on civilians at the Intercontinental Hotel in Kabul where more than 20 people were killed, including 14 foreigners.Afghanistan is witnessing one of its bloodiest periods, following the end of NATO's military mission although it continues its presence in the country for training Afghan forces.In September last year, both the US and NATO had decided to significantly increase their military presence in the country.
