Iraqi authorities have extended a curfew imposed on Baghdad after a massive bomb attack so that vehicles will continue to be banned in city on Saturday, a Defence Ministry spokesman said on Friday, according to Reuters. The curfew was declared after more than 200 people were killed in a coordinate series of bombings in the Shi'ite Sadr City stronghold on Thursday. On Friday, gunmen attacked a Sunni enclave in the city, burning mosques, in an apparent reprisal.
