"The devastation is, I don't have the words for it," Roxas said. "It's really horrific. It's a great human tragedy."
Defense Secretary Voltaire Gazmin said Aquino was "speechless" when he told him of the devastation the typhoon had wrought in Tacloban.
"I told him all systems are down," Gazmin said. "There is no power, no water, nothing. People are desperate. They're looting."
U.S. Marine Col. Mike Wylie surveyed the damage in Tacloban prior to possible American assistance. "The storm surge came in fairly high and there is significant structural damage and trees blown over," said Wylie, who is a member of the U.S.-Philippines Military Assistance Group based in Manila.
U.S. Secretary of State John Kerry said in a statement that America "stands ready to help."
Tacloban is near the Red Beach on Leyte Island where U.S. Gen. Douglas MacArthur waded ashore on October 20, 1944, fulfilling his famous pledge, "I shall return," made in March 1942 after President Franklin D. Roosevelt ordered him to relocate to Australia as Japanese forces pushed back U.S. and Filipino defenders.
Tacloban was the first city to be liberated by U.S. and Filipino forces and served as the Philippines' temporary capital for several months. It is also the home town of former Filipino first lady Imelda Marcos, whose nephew, Alfred Romualdez, is the city's mayor.
The president of the European Commission, Jose Manuel Barroso, said in a message to Aquino that the EC had sent a team to assist the Philippine authorities and that "we stand ready to contribute with urgent relief and assistance if so required in this hour of need."
Weather officials said Haiyan had sustained winds of 235 kilometers per hour (147 miles per hour), with gusts of 275 kph (170 mph), when it made landfall. By those measurements, Haiyan would be comparable to a strong Category 4 hurricane in the U.S., and nearly in the top category, a 5.
