India also pledged one billion dollars for the support and development of "a unified, sovereign, democratic, peaceful, stable and prosperous Afghanistan". Ghani is on a two-day visit to India starting Wednesday.

"The two leaders discussed the regional situation and expressed grave concern at continued use of terrorism and violence in the region for achieving political objectives," a joint statement issued at the end of the meeting said.

"They agreed that this phenomenon presented the single biggest threat to peace, stability and progress in the region and beyond.
"Stressing that elimination of all forms of terrorism, without any discrimination, is essential, they called upon the concerned to put an end to all sponsorship, support, safe havens and sanctuaries to terrorists, including for those who target Afghanistan and India," it said.

PM Modi and Ghani reaffirmed their resolve to counter terrorism and strengthen security and defence cooperation as envisaged in the India-Afghanistan Strategic Partnership Agreement.

India and Afghanistan also exchanged agreements on a mutual legal assistance treaty, for peaceful uses of outer space and an extradition treaty.

The documents were exchanged in the presence of Prime Minister Narendra Modi and visiting Afghan President Ashraf Ghani.

"One more step in closer ties. Exchange of agreements on MLAT, Extradition & peaceful uses of outer space following talks," External Affairs Spokesperson Vikas Swarup said in a tweet.

The Union Cabinet had on Monday approved the inking of an Extradition Treaty between India and Afghanistan.

The treaty would provide a legal framework for seeking extradition of terrorists, economic offenders and other criminals from and to Afghanistan. Ghani arrived here on Wednesday on a two-day visit.
