VOICE-OVER SCRIPT:

FRANTIC PAKISTANIS SIFTED THROUGH RUBBLE SEARCHING FOR SURVIVORS AFTER A CAR BOMB EXPLODED OUTSIDE A MOSQUE IN A SHIITE NEIGHBORHOOD -- KILLING DOZENS AND INJURING MORE THAN 140 OTHERS.

IT HAPPENED AS WORSHIPPERS WERE LEAVING EVENING PRAYERS AT THE MOSQUE.

NO GROUP IMMEDIATELY CLAIMED RESPONSIBILITY FOR THE BLAST, BUT SHIITE MUSLIMS -- A MINORITY IN PAKISTAN -- HAVE BEEN INCREASINGLY TARGETED BY SUNNI MILITANT GROUPS.

THAT'S ESPECIALLY TRUE IN KARACHI -- AN ECONOMIC HUB IN SOUTHERN PAKISTAN -- THAT HAS SEEN YEARS OF POLICE, SECTARIAN AND ETHNIC VIOLENCE.

SUNDAY'S BOMBING WAS THE THIRD LARGE SCALE ATTACK AGAINST SHIITE MUSLIMS IN PAKISTAN THIS YEAR.

TWO EARLIER ATTACKS HAVE KILLED NEARLY TWO HUNDRED SHIITES.

AS VICTIMS' RELATIVES GRIEVE -- MANY ARE ALSO ANGRY.

"WHERE IS THE GOVERNMENT?" - ONE WOMAN SAID.

"TERRORISTS ROAM FREE. NO ONE DARES TO CATCH THEM," SHE SAID.
