On 26/11 Mumbai attacks, the Pakistan based group LeT was accused of being responsible for those attacks. On 6/12 Kabul, the Taliban have denied responsibility for the attacks, & the Pakistan based group LeJ has accepted responsibility for the attacks. What we can sure about is that Pakistan will be put under pressure for today's events in Kabul, as the US media is doing right now. The LeJ is a Punjab based Jihadi group that has been aiding AQ & TTP terrorists in the FATA, as well as aiding sectarian violence in parts of Balochistan, & else where in the country. The LeJ has its strongholds in Punjab, & plays second fiddle elsewhere in the country, working as an umbrella group for other militant groups. They have not had any presence in Afghanistan, & it is not clear how they could have been responsible for such coordinated attacks deep inside Afghan territory in Kabul & Mazar-e-Sharif (in Northern Afghanistan close to the Uzbek border). It is unrealistic that the LeJ, which has no presence in Afghanistan, could have be responsible for such coordinated attacks deep inside Afghan territory.
