"We haven't really tried to directly kill parasites in the mosquito before this, because we were just killing the mosquito," says researcher Dr Alexandra Probst, from Harvard.However, she says that approach is "no longer cutting it".

The researchers analysed malaria's DNA to find possible weak spots while it is infecting mosquitoes.They took a large library of potential drugs and narrowed it down to a shortlist of 22. These were tested when female mosquitoes were given a blood-meal contaminated with malaria., the scientists describe two highly effective drugs that killed 100% of the parasites.

The drugs were tested on material similar to bed nets."Even if that mosquito survives contact with the bed net, the parasites within are killed and so it's still not transmitting malaria," said Dr Probst.

"I think this is a really exciting approach, because it's a totally new way of targeting mosquitoes themselves."

She says the malaria parasite is less likely to become resistant to the drugs as there are billions of them in each infected person, but less than five in each mosquito.UN bodies estimate 600 trucks a day are required to begin tackling Gaza's chronic humanitarian crisis.

Earlier, the UN's humanitarian chief Tom Fletcher told the BBC thousands of babies could die in Gaza if Israel does not immediately let aid in.Speaking to the BBC's Today programme, Mr Fletcher said: "There are 14,000 babies that will die in the next 48 hours unless we can reach them."

When pressed on how he had arrived at that figure, he said there were "strong teams on the ground" operating in medical centres and schools - but did not provide further details.The BBC later asked for clarification on the figure from the UN's Office for the Coordination of Humanitarian Affairs (UNOCHA), which said: "We are pointing to the imperative of getting supplies in to save an estimated 14,000 babies suffering from severe acute malnutrition in Gaza, as the IPC partnership has warned about. We need to get the supplies in as soon as possible, ideally within the next 48 hours."
