Japanese medics working to help victims of the Philippines typhoon have deployed wireless mobile X-ray kits using tablet computers, a world first in a disaster zone, a team spokesman said Saturday.

The technology, which was developed after the huge tsunami that hit Japan in 2011, allows doctors to take a look inside patients instantly, and even lets them enlarge the image with familiar iPad gestures.

Prime Minister David Cameron announced Saturday that Britain was providing a further $48 million to help the relief effort after the devastating typhoon in the Philippines.

"Today I can announce that we are providing a further 30 million pounds ($48 million) to support the United Nations and Red Cross emergency appeal" to help survivors of Typhoon Haiyan, he told reporters.

The United Nations has received $72 million for its relief fund for the disaster-stricken Philippines with Gulf countries the key contributors, a top U.N. humanitarian official said Friday.

Kuwait and United Arab Emirates have each given $10 million to the U.N. appeal for $301 million to help survivors of Typhoon Haiyan, John Ging, the U.N. humanitarian operations director told a news conference.

Hong Kong said Friday it will contribute $5.16 million to a fund that can be used to help the typhoon-stricken Philippines, after drawing fire for sticking to a deadline on sanctions against Manila over a 2010 hostage crisis.

The city's legislative body voted for the injection of HK$40 million ($5.16 million) into an existing disaster relief fund, boosting its total amount to HK$49 million, which aid groups can then apply for, the government said in a statement late Friday.

Fears that the dire situation among desperate typhoon survivors in the Philippines would tip into violence receded Friday, as relief operations scaled up and a reinforced police presence deterred looters.

At Tacloban airport, which had witnessed frenzied scenes earlier in the week as crowds fought for a seat on any plane leaving the devastated city, a semblance of order had been restored.

China should send warships to aid the typhoon-hit Philippines and counter U.S. and Japanese influence, state-run media said Friday, as Beijing comes in for criticism for its relatively meagre donation to the stricken nation.

The call came after China said Thursday it would provide a further $1.6 million aid to the Philippines, mainly in tents and blankets, following condemnation of its initial response of a $100,000 government donation, matched by the Chinese Red Cross.

The U.S. military said Thursday it was deploying 1,000 Marines to support emergency relief operations in the Philippines following Super Typhoon Haiyan.

About 900 troops will board two U.S. Navy amphibious ships -- the Japan-based USS Germantown and USS Ashland -- and are due in the Philippines in about six days, Marine Forces Pacific said in a statement.

Britain will send the helicopter carrier HMS Illustrious to the Philippines to help with relief efforts after Super Typhoon Haiyan, Prime Minister David Cameron said Thursday.

"I can announce Britain is sending the carrier HMS Illustrious to help with #TyphoonHaiyan," Cameron, who is heading to a Commonwealth summit in Sri Lanka, said on his official Twitter account.

A huge U.S. aircraft carrier arrived off the coast of the typhoon-hit Philippines Thursday, offering hope of a dramatic uptick in aid to destitute survivors as officials buried scores of rotting corpses.

The USS George Washington, with 5,000 sailors aboard, headed an eight-strong flotilla of U.S. vessels bearing badly needed equipment, supplies and expertise for the thousands left homeless and hungry by one of the strongest storms in history.

The Israeli army dispatched a mission to the Philippines on Wednesday to provide humanitarian assistance to victims of Typhoon Haiyan, a military spokeswoman said.

The mission consists of 148 specialists who will provide medical as well search-and-rescue services in Tacloban, the Philippine city worst hit by last week's deadly storm.
