KABUL (AFP) - Afghan senators demanded Tuesday that international troops operating in Afghanistan be brought under the country's law to make them accountable for mounting civilian casualties. Parliament's upper house, or Meshrano Jirga (House of Elders), said it would draw up legislation to cover the operations of the US-led and Nato-led troops helping the government fight a Taliban-led insurgency. The demand came during a heated debate over the number of civilians being killed in international military action against insurgents, mainly air strikes, with a series of deadly incidents in the past weeks. "It was decided that the presence of foreign forces must be legalised under a law," a secretary to the house, Aminuddin Muzafari, told reporters afterwards. "There should be a programme, a law, under which these forces conduct their activities. We will make that law," he said. Any proposed law would have to have the approval of both houses of parliament as well as President Hamid Karzai. The senators also demanded a timetable for the withdrawal of the soldiers, now numbering around 70,000. The forces have said they would leave when the government is able to take care of security itself. The upper house debate centred on an incident in which Afghan police accused troops with Nato's UN-mandated International Security Assistance Force of killing civilians in the province of Kapisa near Kabul at the weekend. "Every time they have killed civilians we have condemned it," said another member of the upper house, Baqir Sharifi, after the debate. "But this is not enough. They must be brought under laws and their activities must be controlled." Meanwhile, Afghan forces are back in control of a remote district that the Taliban captured three weeks ago, local officials said Tuesday. Afghan and international forces had late Sunday moved into Ajristan district centre, about 200km southwest of Kabul, a provincial government spokesman said. The white flag of the Taliban had been removed and replaced with the Afghan flag after the rebels fled without resistance, Ghazni government spokesman Ismail Jahangir told AFP. Six "enemies" were meanwhile killed in a military operation in Paktika province on the border with Pakistan Monday, the Defence Ministry said in a statement. A British soldier and four civilians have died after being wounded in a suicide attack in Kabul, Nato and British forces said Tuesday, a day after the blast killed three Afghans outright. A suicide attacker slammed a car bomb into a patrol of the NATO-led International Security Assistance Force (Isaf) on a busy road in the capital on Monday. The insurgent Taliban claimed responsibility for the bombing. "It is with deep regret that we must announce that a soldier from 16 Signal Regiment has died and two more from the same regiment were wounded in a suicide attack on a vehicle patrol in Kabul," the British Ministry of Defence said. A Canadian soldier was killed Monday in Afghanistan, the 90th to die in the Canadian mission there, the Ministry of Defence said in Ottawa.
