After the 2008 Mumbai attacks, India temporarily suspended all formal dialogue with Pakistan. Further straining the ties between the two south Asian nations, India recently announced the arrest of a diplomat working at the Indian embassy in Islamabad over suspicion that she was spying on behalf of Pakistani intelligence services. The Prime Ministers of both countries, however, have decided to meet at a summit of south Asian leaders in Bhutan. It has been indicated that Indian Prime Minister Manmohan Singh will likely address the continued threat of Pakistan-based fighter groups, such as those blamed for the Mumbai attack, and Pakistani Prime Minister Yousuf Raza Gilani is expected to bring up the possibility of continuing the dialogue involving long-term peace. This discussion will represent one of the few contacts between the two countries since senior foreign ministry officials met in Delhi in February.
