QUETTA, Pakistan — Angry Pakistani Shiites considered launching a new round of protests against the government in a southwestern city on Sunday, a day after a bombing killed at least 81 people, mostly from their sect, in the second such attack in as many months.

Saturday's blast at a produce market in Quetta underlined the precarious situation for Shiites living in a majority Sunni country where many extremist groups don't consider them real Muslims. Some 160 people were also wounded in the blast.

Friends and relatives of the dead gathered in the hundreds around Shiite mosques, where some 60 victims were laid out in coffins as religious leaders debated whether to protest the bombing by refusing to bury the dead as they did after January's attack.
