North Korea says it is facing the worst drought in a century, sparking fears of worsening food shortages.

The drought has reportedly also hit rice paddies in parts of South Korea

State news agency KCNA said main rice-growing provinces had been badly affected and more than 30% of rice paddies were "parching up".

Hundreds of thousands of North Koreans are believed to have died during a widespread famine in the 1990s.

This drought is unlikely to be as deadly because of recent agricultural reforms, correspondents say.

The United Nations World Food Programme says North Korea regularly faces significant food shortages and currently about a third of children in the country are malnourished.

KCNA said granaries in the provinces of South Hwanghae, North Hwanghae, South Phyongan and South Hamgyong were "badly affected".

It added that it was planting other crops in rice paddy fields of drought-stricken areas to "reduce damage".

Last year the country saw its lowest rainfall in 30 years.

The BBC's Stephen Evans in Seoul says that since the famine in the 1990s, North Korea has allowed more privately organised farming and output has risen.

For this reason, food shortages caused by the current drought are unlikely to be on the same scale, he says.

Other countries, including South Korea, regularly send aid to the North. In April the UN called for $111m (£71m) to fund humanitarian activities in food, nutrition, agriculture and sanitation.
