Rain lashes Myanmar cyclone survivors

As more foreign aid trickled into the former Burma, critics ratcheted up the pressure on its military rulers to accelerate a relief effort that is only delivering an estimated tenth of the supplies needed in the devastated delta.

"The response of the regime in Burma to this crisis has been absolutely callous and those paying the price of this callousness have been the long-suffering Burmese people," Australian Prime Minister Kevin Rudd told parliament.

An Australian air force plane landed in Yangon, Myanmar's main city, with 31 tonnes of emergency supplies, a day after the first U.S. military aid flight arrived in a country Washington has described as an "outpost of tyranny".

Two more U.S. flights arrived on Tuesday as part of a "confidence building" effort to prod Myanmar's reclusive generals into allowing a larger international relief operation 11 days after the disaster left up to 100,000 dead or missing.

France, Britain and Germany called on Tuesday for the world to deliver aid without the junta's agreement, using a little used U.N. principle of the "responsibility to protect".

Myanmar state television said the official death toll had risen to 34,273 from nearly 32,000 and 27,838 were missing.
