Dozens of countries sign deal to curb bombing in urban areas

Campaigners hope agreement will change military norms, though it was not endorsed by countries including Russia, Israel and China

Eighty countries led by the US, UK and France have signed a declaration in Dublin pledging to refrain from urban bombing, the first time countries have agreed to curb the use of explosive weapons in populated areas.

The international agreement is a product of more than three years of negotiation - predating the war in Ukraine - but was not endorsed by several major military powers, including Russia, China, Israel and India.
