Afghani Suicide Bombing at Courthouse

Earlier today a group of Taliban members attacked a courthouse on the western border of Afghanistan and Iran. 50 people were killed and 90 people were injured. The Taliban announced they were behind the attacks, and that they were attempting to free some of their members who were imprisoned at the courthouse. They dressed up as soldiers, all wearing bomb vests. They blew up a military truck filled with explosives, and the remaining militia broke out guns and began shooting. This is the highest death toll of a suicide attack since 2011 in Afghanistan. Their attempts did not succeed, the prisoners were all accounted for. The surrounding banks and governor's office were also effected, and many were injured who were nearby. Should this be something we need to worry about? Is this the start of another long strand of suicide bombings? What is the United States as a nation going to do about it, if anything? Here's the link:
