What India and Pakistan don't agree on

Here are some of the main points of contention: 

• Kashmir – The Muslim-majority state has been divided since partition, with India
  

  controlling most of it; Pakistan claims the whole state and is accused of training Islamist guerrillas to fight Indian rule; in addition to various armed groups, several political parties oppose Delhi's rule and organise frequent protests and strikes; some want to join Pakistan, others want independence.

• Cross-border violence – India accuses Pakistan’s secret services of being behind
  

  many bombings and other attacks on its soil; it says Islamabad has failed to crack down on Lashkar-e-Taiba, which it blames for the Mumbai attacks; a senior civil servant claims a confession by a US-born Islamist shows that Pakistan’s secret services, the ISI, masterminded the 2008 slaughter.

• Afghanistan – Pakistan regards Afghanistan as its back yard, and the ISI helped
  

  train both anti-Soviet fighters and the Taliban; India has increased its investment and influence since the 2001 US-led invasion, leading to Pakistan fearing that it will be encircled.

• Water – Farmers in the Pakistani breadbasket province of Punjab accuse India of reducing the Chenab river to a trickle; Pakistan claims that a power project in Kashmir violates the 1960 Indus Water Treaty.

There is at least one thing these fractious neighbours have in common - they both have nuclear weapons.
