Some 75% of Indonesia's capital, Jakarta, is now affected by massive floods, local officials say.

The officials, from the city's flood information centre, say the death toll from the flooding has reached 25 - mostly by drowning or electrocution.

Some 340,000 people have been made homeless, and the officials say there is little prospect of an early improvement in the situation.

There are fears that polluted water could be spreading disease.

"As of today [Monday], 75% of Jakarta remains flooded," Anwar Arifin, from Jakarta's flood information centre, was quoted as saying by the Associated Press news agency.

Several days of torrential rain have caused rivers to burst their banks, sending muddy water up to 3m (10ft) deep into homes and businesses.

Staff manning a key floodgate in the east of the capital said it had failed and the water flowing in had caused the main canal to burst its banks.

Electricity and water supplies remain cut in large areas of the city, and major train lines and some roads have been closed.

Hundreds of residents are still holding out on the second floor of their homes, either trapped or unwilling to move, the BBC's Rebecca Henschke in Jakarta says.

Many of the homeless are sheltering in schools and mosques.

Medical teams on rubber rafts are working in the worst affected areas of the city, while thousands of extra police have been deployed to help with evacuation efforts.

There are fears about the spread of diseases - like diarrhoea and dysentery - among people who have been living without clean drinking water for days.

The government is facing renewed criticism that it could have done more to prevent this disaster, our correspondent says.

The floods are said to be the worst to hit Jakarta for five years.

Meteorologists have warned the downpour is likely to continue for another week, and with heavy rains falling on hilly regions to the south, more flooding is threatened.
