We are now joined live by our CCTV correspondent Nathan King, who is in our New York studio. Hello Nathan.

Q1. The latest word is the headquarters of the UN Stabilization Mission in Haiti and other UN buildings in the capital of Port-au-Prince collapsed. About 150 UN workers are still unaccounted for. You briefed us on the UN's response to the quake in Haiti hours ago. Are there any new plans?

Q2. We know US President Barack Obama has expressed his deepest sympathies to UN Secretary-General Ban Ki-moon for the losses. Are there any further measures the White House is taking to help?
