At least five killed as three blasts rock Kabul: official

Some observers say the insurgents are increasing attacks to gain greater leverage in the talks

At least five people were killed Thursday in a suicide bombing in Kabul, an official said, adding that two other blasts had also hit the Afghan capital.

The bombing comes amid an increase in violence in Kabul and around Afghanistan, where the war is taking a continued toll even amid a US-led effort to make a peace deal with the Taliban.
