TIMELINE - Flashpoints and flare-ups in India-Pakistan ties

Reuters - Pakistani President Asif Ali Zardari telephoned India's prime minister on Friday to condemn attacks in the Indian city of Mumbai that killed at least 121 people and suggested "non-state actors" were responsible.

On Thursday, Indian Prime Minister Manmohan Singh pinned blame on militant groups based in India's neighbours, usually an allusion to old rival Pakistan, raising prospects of renewed tension between the nuclear-armed rivals.

Here is a timeline charting some key moments of tension between the two countries.

* Aug. 14, 1947: Muslim Pakistan is formed from partition of India at end of British colonial rule, amid bloodletting between Hindus and Muslims.

* Oct 1947: The two countries fight their first war over Kashmir, after its Hindu ruler opts to join secular India rather than Islamic Pakistan.

* Jan 1949: U.N. Security Council-ordered ceasefire takes effect in Kashmir.

* Sept. 1965: Second war over disputed Kashmir region. Combat ends after U.N. calls for ceasefire.

* Dec. 1971: Third India-Pakistan war over East Pakistan. It ends with surrender of 90,000 Pakistani troops and leads to creation of Bangladesh, formerly East Pakistan.

* Dec 1989: Jammu and Kashmir Liberation Front rebels kidnap daughter of Indian home minister, demand five separatist leaders are freed for her release. The government gives in, in a move seen as a major boost for separatist groups.
