Nepal said it "has received communications" from four member-states - Afghanistan, Bangladesh, Bhutan and India - in which they conveyed their inability to participate in the 19th SAARC summit on November 9-10 stating that the current regional environment is "not conducive" for the successful holding of the Summit.
"We have taken this development seriously," it said in a statement posted on its Foreign Ministry's website.
Under the SAARC Charter, the summit is automatically postponed or cancelled even if one member country skips the event.
The four countries have pulled out of the summit, indirectly blaming Pakistan for "creating an environment which is not right for the successful holding" of the meet.
That development came after tensions ran high between India and Pakistan after militants stormed an Indian Army base in Uri on September 18, killing 18 soldiers. The militants belonged to Pakistan-based Jaish-e-Mohammad terrorist group.
