China has disputed Germany's claim that it targeted a military plane with a laser fired from a warship, as a diplomatic spat between the two countries deepens.

Germany accused China of attempting to disrupt one of its aircraft earlier this month as it was taking part in European Union-led operations aimed at protecting ships in the Red Sea from missiles launched by Yemen's Houthi rebel group.

The German foreign ministry has summoned the Chinese ambassador and described the incident as "entirely unacceptable". China's envoy to the EU has also been summoned by the bloc.

Beijing has pushed back, saying Germany's account was "totally inconsistent with the facts known by the Chinese side".
