The Taliban has claimed responsibility for the attack.

Despite the near 17-year US-led campaign in Afghanistan, Taliban militants still maintain control over vast swathes of territory and are capable of launching attacks on troops and civilians in urban centers like Kabul with deadly regularity.

Islamic State (IS, formerly ISIS) has also rooted a presence in several eastern provinces.

The worsening security situation has seen US President Donald Trump move away from claims during the presidential that the US should stop being the world’s policeman, instead overseeing a troop surge in Afghanistan.

The UK has also promised to double its troop commitment to the train and assist mission of Afghan troops it is overseeing, with a further 400 troops to begin deployment from August.

In addition to attempts to get a handle on the deteriorating security situation, US aid money aimed at curbing Afghanistan’s rampant poppy trade had done little to topple it as the world’s number one opium producer.

A recent report by the Special Inspector General for Afghanistan Reconstruction (SIGAR), Afghanistan’s reconstruction watchdog, found that despite spending $8.62 billion on counternarcotics efforts in the country between 2002-2017, the US had failed to reduce the drug-related threats to Afghanistan “in a meaningful way,” with opium poppy remaining the “largest cash crop” in Afghanistan.

It also found that irrigation projects funded by Washington to promote the growing of alternative crops contributed to “increased poppy cultivation.”
