Dhaka - Bangladesh Nobel laureate Muhammad Yunus Tuesday called for national unity to fight the global meltdown, which has started affecting the country's impoverished economy.

"It needs great courage and national unity to face the problem nationally," said the micro-credit guru, who won the Nobel peace prize with his Grameen Bank in 2006.

Speaking after a meeting of a national task force, he said food, energy, power, port and agriculture should have priority when it comes to dealing with the crisis.
