Saleh al-Arouri is the most senior Hamas figure killed since the Israel-Hamas war began in October.

The deputy head of Hamas, the Palestinian group which rules Gaza, has been killed in a blast in Lebanon, a senior Hamas official has told the BBC.

Local media said Saleh al-Arouri was killed in an Israeli drone attack in the south of the capital, Beirut.

At least three other people were reportedly also killed in the incident. Israel has not commented.
