'We stand together and will face all eventualities,' Zardari added, pointing to the threats terrorists posed to national interests.

The three countries agreed that terrorism was a regional phenomenon that necessitated a comprehensive, concerted and coordinated approach with full participation of the states and local communities.

'Militancy, separatism, extremism and organized crimes undermine regional peace and stability and pose a threat to the security of all regional states,' a joint declaration signed by the three presidents said.

'Tajikistan, Afghanistan and Pakistan declare their readiness to cooperate in effectively addressing the menace of terrorism and organized crime,' the declaration added.
