An unexpected side-effect of the flooding in parts of Pakistan has been that millions of spiders climbed up into the trees to escape the rising flood waters.

Last Friday, in Afghanistan's mountainous northeastern province of Badakhshan, an enormous landslide took place, burying much of a small village, and killing hundreds. Officials say that at least 300 residents of Abi Barik village were killed, but are uncertain about exact numbers, cautioning that the final number could be 500 or more. Rescue teams gave up hope on Saturday of finding any survivors, focusing energy on helping the hundreds suddenly made homeless. Many of the surviving families have struggled to get aid. Some have gone to nearby villages to stay with relatives or friends, while others have slept in tents provided by aid groups.
