I'm sure this, like similar bombings, is a direct result of fundamentalist Muslim outrage over peaceful actions between India and Pakistan in light of the lat serious earthquake in that region.
Whenever any Muslim government enters into promising relationships with a non-Islamic statements, these fiends come crawling out of the woodwork to maim and kill inncoent people - generally but not always the non-Muslims.
This is merely yet another in a long and growing series of events which demostrates the esential cult nature of that belief system and its incopatibility with any form of civlized governmnet or society.
The reports from the Palestinians show that the Arabs have killed more of each other than the IDF has, and the reports from Iraq show that the Muzzi's have killed 26,000 Iraq Muzzi's so far.
Islam is very indescriminate with who it kills. The object is killing, not politics or military goals it seems.
