News Digest: Yemen war: Saudi-led air strike on bus kills 29 children; Hip hop star dies after a seizure aged 37

At least 29 children have been killed and 30 wounded in a Saudi-led coalition air strike in Yemen, the International Committee of the Red Cross says.

The children were travelling on a bus that was hit at a market in Dahyan, in the northern province of Saada.

The health ministry run by the rebel Houthi movement put the death toll at 43, and said 61 people were wounded.

It insists it never deliberately targets civilians, but human rights groups have accused it of bombing markets, schools, hospitals and residential areas.

Meanwhile the new UN special envoy to Yemen, former British diplomat Martin Griffiths, is planning to invite the warring parties to Geneva in September to discuss a framework for negotiations.
