Afghan intelligence officers seized two trucks transporting hundreds of kilogrammes of bomb-making materials in a province near the capital, NATO said on Tuesday. The discovery comes after Kabul saw a surge in suicide and other bomb attacks last month, with officials saying bomb-making cells were operating around the city.The materials were discovered at the weekend in a large “jingle truck”, the colourfully decorated cargo vehicles that are a common sight on Afghanistan’s road, and a smaller truck, the NATO-led International Security Assistance Force said in a statement. They were transporting more than 150 34-kilogramme bags of ammonium nitrate and over 159 cans of suspected magnesium paste, both important elements in the making of explosives, it said. The material was found in the province of Laghman on the border of Kabul province.
