Heavy Rains and Eid Animal Sacrifices Create Rivers of Blood in Dhaka, Bangladesh Heavy rains mixed with animal sacrifices for Eid, turning the streets red.

 -- Rivers of blood flowed through the streets of Dhaka, Bangladesh, on Tuesday morning after heavy monsoon rains mixed with animal sacrifices for the Muslim festival of Eid al-Adha.

The annual holiday, known as the Feast of Sacrifice, is the second biggest celebration of the year for Muslims.

Families mark the day by slaughtering livestock in commemoration of God's test of faith on the Prophet Ibrahim. The meat of the sacrificed animals is then shared among family, friends and those in poverty.

Though the slaughters create some amount of blood on the streets every year, the heavy downpour turned the streets much redder than usual.

Authorities in Dhaka said they designated several places in the city where residents could slaughter animals, but the rains prevented most from accessing those areas.

Many residents criticized city officials for Dhaka's faulty drainage system, which has long been a problem, the BBC reported. The news outlet added that a waste management official with Dhaka South City Corporation told a local newspaper they were working to resolve the flooding issue.
