An explosion followed by gunfire in Kabul on Friday claimed the lives of at least two attackers and wounded a small number of civilians. The Taliban claimed responsibility for the attack, which appeared to have been aimed at offices of the International Organization for Migration and stretched over several hours as Afghan security forces tried to hunt down those responsible.
As night fell in Kabul, it was unclear whether the incident was over or not.
For years, reports have suggested that Afghanistan is sitting on massive deposits of copper, gold, iron and rare earth minerals valued up to $3 trillion. This provides hope for a future economy that would not have to rely so heavily on foreign donations.
But with an uncertain political, regulatory and security environment, international investors are hesitant. And it could be many years before Afghanistan begins extracting its mineral wealth.
Early casualty reports indicate that a powerful suicide car bombing Thursday in Kabul killed at least seven Afghan civilians, four foreign civilian contractors who were working for international forces and two members of the international military force.
Dozens more people were reportedly injured by the blast in Afghanistan's capital city.
