The U.S. military on Wednesday sent more cargo planes and tilt-rotor Osprey aircraft to bolster relief efforts in the Philippines, hoping to reach areas cut-off by a deadly typhoon.

Four MV-22 Ospreys have departed from the U.S. Futenma base in Japan bound for the Philippines, expanding the number of Osprey aircraft involved in the emergency work to eight, the U.S. Marine Corps said in a statement.

Kuwait's Emir Sheikh Sabah al-Ahmad Al-Sabah on Wednesday ordered that $10 million in urgent relief aid be sent to typhoon-ravaged Philippines, where thousands of people are feared dead.

"In sympathy with the victims of the destructive typhoon that ravaged the Philippines ... the emir ordered $10 million in urgent relief aid to help face this humanitarian catastrophe," the official KUNA news agency cited State Minister for Cabinet Affairs Sheikh Mohammad Abdullah Al-Sabah as saying.

Dozens of psychologists were starting work in the typhoon-raked Philippines Wednesday to help dazed survivors deal with the psychological fallout of one of the country's worst ever disasters.

The operation is an early attempt by health professionals to head off what they fear could be serious problems down the road, even as the physical scars from the tragedy begin to heal.

Thousands of people jostled and begged for seats Wednesday on scarce flights out of a Philippine city demolished by a super typhoon, as anger at the slow pace of aid reaching the disaster zone turned deadly.

News emerged that eight people were crushed to death Tuesday when a huge crowd of survivors from Haiyan rushed a government rice store in Alangalang town, 17 kilometers (10 miles) from the devastated city of Tacloban.

Grammy-winning Spanish singer Enrique Iglesias, whose mother is from the Philippines, on Tuesday urged his fans to give money to help victims of the devastating Typhoon Haiyan.

"HELP THE PHILIPPINES! People in the Philippines need our help right away! Please consider donating to Haiyan disaster relief. You'll feel good that you did," the 38-year-old wrote on his official website beside a link to the web page of the American Red Cross.

President Barack Obama spoke to Philippine President Benigno Aquino Tuesday to express sorrow for the destruction left by Typhoon Haiyan and to coordinate U.S. help.

Obama expressed America's "deep condolences for the lives lost and the damage caused" by the storm that is feared to have killed more than 10,000 people, his spokesman Jay Carney said.

In the withered heart of the Philippines' typhoon disaster zone, defeated survivors abandoned hopes Tuesday of a dignified burial for their loved ones and tried to flee aboard military planes.

Four days after Super Typhoon Haiyan destroyed entire towns across the central Philippines, leaving more than 10,000 people dead, the worst-hit islands of Leyte and Samar remained largely cut off.

The United Nations on Tuesday began an appeal for almost a third of a billion dollars in aid to help people hit by the huge typhoon that raked the Philippines last week.

"We've just launched an action plan focusing on the areas of food, health, sanitation, shelter, debris removal and also protection of the most vulnerable with the government and I very much hope our donors will be generous," humanitarian chief Valerie Amos told reporters in Manila.

Philippine troops killed two armed insurgents who attacked an aid convoy en route to typhoon-devastated Tacloban on Tuesday, the military said, as soldiers were deployed to quell looting by hungry survivors.

Bodies still littered the streets of the city, where the United Nations fears 10,000 people could have died when the category-five Haiyan struck on Friday.

U.S. and British warships were deployed Tuesday to the typhoon-ravaged Philippines where well over 10,000 people are feared dead and countless survivors are begging for help in rain-soaked wastelands.

Four days after Super Typhoon Haiyan destroyed entire coastal towns in mostly poor central islands with record winds and tsunami-like waves, the magnitude of the disaster continued to build with almost unimaginable horror.
