Afghan President Hamid Karzai has addressed Nato leaders at a summit in Istanbul, urging them to send promised extra peace-keepers immediately. Nato has agreed to increase its forces from 6,500 to 10,000 to bolster security during September elections. Mr Karzai thanked the leaders, but added: \"I would like you to please hurry... come sooner than September.\" He again insisted the polls must be held on time despite a UN warning that security concerns might force a delay. Mr Karzai was addressing the leaders of the 26-member military alliance on the second and final day of their summit in Istanbul. He said: \"I welcome very much your decision yesterday to send us security forces to help us with the elections. \"But... we need security forces today in Afghanistan to provide a secure environment for elections for the Afghan people and beyond.\" Mr Karzai had wanted extra peace-keepers for the more unstable areas, particularly the south and east. But correspondents say those areas are likely to be left to a 20,000-strong US-led combat force. Mr Karzai had earlier rejected suggestions that the additional troops would make no difference to security in Afghanistan. \"Kabul has about 5,000 troops and Kabul has been a very safe place for Afghanistan and for the international community,\" he said. \"If the strength goes to 10,000 troops and if that\'s deployed around the country, where we don\'t have Nato forces right now, that will bring about a lot of difference to the security of life, to the citizens of Afghanistan where they\'re deployed.\" During the summit France rejected a request by the US that a recently formed Nato rapid reaction force be deployed during the September elections. \"It\'s not made for that, French President Jacques Chirac told reporters. Most of the troops in the unit are French. (BBC)
