British Prime Minister David Cameron, German Chancellor Angela Merkel and French President Nicolas Sarkozy on Monday called on Iran to "immediately" suspend its nuclear programme, dpa reported.
"We will not accept Iran acquiring a nuclear weapon," the three leaders said in a joint statement.
"We call on Iran's leadership immediately to suspend its sensitive nuclear activities and abide fully by its international obligations," they said, while leaving the door open for "serious and meaningful negotiations about its nuclear programme."
