"In two or three weeks, there won't be any more food aid inside Afghanistan, and it isn't self-sufficient at all," Christiane Berthiaume, spokeswoman for the World Food Program, said Tuesday in Geneva, Switzerland.
At least 5 million Afghans need help, and the World Food Program is currently feeding 3.8 million of them, she said.
"They are already hungry and we are already seeing a sign of pre-famine with reports of people being paralyzed because they had eaten poisonous plants," she said.
Meanwhile, thousands of Afghans have been gathering on islands along the Pyandzh River that marks much of Afghanistan's border with Tajikistan, Russian Federal Border Guard Service spokesman Sergei Ivanchenko said in Moscow.
Ivanchenko said 12,000 refugees were on the islands as of earlier this month, with another 120,000 in other areas butting up against the Tajik border, and predicted those numbers would soar after airstrikes.
Tajikistan is not ready to take in a single one, he said Tuesday.
