Karzai and Singh discuss security

Afghan President Hamid Karzai has met India's PM Manmohan Singh in Delhi, with regional security the key issue.

Mr Karzai's office said he was there to convey "solidarity" in the wake of the November attacks on Mumbai (Bombay).

After the talks the leaders said they were urging all countries to try to tackle terrorist groups.

Correspondents say this was a reference to Pakistan. India believes "elements" there helped carry out the attacks, which left more than 170 people dead.

Pakistan denies any involvement.

Afghanistan also has a difficult relationship with Pakistan, long criticising Islamabad for not doing enough to stop militants crossing the border to launch attacks.

Biden talks

India and Afghanistan share cordial relations and the BBC's Sanjoy Majumder in Delhi says these talks were substantive.

The leaders said the Mumbai attacks showed that terrorism was a threat to all humanity and, in what our correspondent says was an oblique reference to Pakistan, called on all countries to fully comply with international obligations to prevent terrorist groups from operating within their borders.

India also announced that it had completed a major power project in Afghanistan that would supply electricity to the capital, Kabul.

And it said it would send 250,000 tonnes of wheat to help the country tide over its current food crisis.

Mr Karzai arrived on Sunday and is expected to return to Kabul on Monday after the talks.

Afghanistan's foreign minister and national security adviser joined Mr Karzai on the visit.

On Saturday, Mr Karzai met US Vice-President-elect Joe Biden in Kabul for talks on Afghanistan's reconstruction and the fight against militants.

Correspondents say the security situation in Afghanistan - and the fight against Taleban insurgents there - is one of the incoming US administration's foreign policy priorities.
