The world in brief

An Israeli strike on Nabatieh, a town in southern Lebanon, killed the mayor and at least 15 other people. Lebanon’s health ministry, meanwhile, said it would implement a “national cholera plan” after a case of the disease was detected. Reuters reported that Binyamin Netanyahu, Israel’s prime minister, held an emergency meeting after America warned that Israel must improve humanitarian conditions in the enclave or face restrictions on weapons shipments. More aid lorries reached Gaza in recent days.

Kamala Harris sat for a feisty interview with Fox News. The right-wing station is hostile territory for her. She nonetheless sought to persuade its Trump-supporting viewers that the former president was unfit for office, repeatedly calling him “unstable” and criticising his description of some Democrats as “the enemy within”. She denied that her presidency would simply be a continuation of Joe Biden’s.
