Separatist politicians from Indian Kashmir are making an unprecedented trip to Pakistani Kashmir for talks on the disputed region's future.

The officials from Indian Kashmir's main separatist political alliance, the All Parties Hurriyat Conference, are using the recently launched bus service between the two regions.

They plan to meet with leaders of Pakistani Kashmir and Pakistan-based rebel groups which have been involved in a violent insurgency in Indian Kashmir for the past 15 years.

The Hurriyat alliance seeks an independent Kashmir. But its hard-line pro-Pakistani splinter group has rejected the invitation, accusing Islamabad of diluting its stand over Kashmir and appeasing New Delhi.

India has previously denied permission to Hurriyat leaders to visit Pakistan, saying the Kashmir dispute is India's internal matter.
