Can new Pakistan-Afghanistan tensions lead to another border clash?

Relations between Pakistan and Afghanistan have been tense since the Taliban took power. Pakistan has summoned a senior Afghan diplomat after an attack claimed by the Pakistan Taliban, which has carried out further attacks against security forces. Islamabad accuses Kabul of backing the fighters, a claim denied by Afghanistan. Mediation efforts by several countries have led to a pause in fighting, but the two sides continue to target each other, including a Pakistani strike on a drug rehabilitation centre.
