A bomb blast at a rally in the city of Quetta, Pakistan, killed at least 55 people and left over 100 wounded on Friday. The attack follows three bombings in Lahore earlier this week, for which the Taliban claimed responsibility. Friday's attack took place in a busy commercial area at a Shi'ite rally in which people gathered to express support for the Palestinian people. Alongside disease, crop destruction and homelessness, a major aspect of the fallout from the floods that have devastated the South Asian nation is its army's inability to contend with Taliban attacks. The Pakistani Taliban, which American officials say was behind the failed Times Square bomb attempt, was added to the U.S. terrorism blacklist this week.
