Streets in the Bangladeshi capital Dhaka have turned crimson with the blood of animals slaughtered as part of rituals for the Islamic festival of Eid al-Adha. 

Dhaka regularly floods during the rainy season, and authorities keen to minimise festival disruptions to city life had established 1,000 designated sacrifice spots around the city in the run-up to the festival.

But many residents ignored the government's advice and slaughtered animals by their homes or in garages, the Dhaka Tribune reported, and a bout of heavy rain meant the city's streets soon looked like a scene out of a horror movie. 

Many residents complained about the strange situation, saying it was evidence that city authorities had failed to ensure Dhaka's drainage systems were up to scratch. 

A local waste management official conceded that water logging was a long-standing problem for the city. 

“We are still working to solve this issue,” he admitted. “We are hoping that very soon the water-logging problem will be solved,” he added.

For Muslims, Eid al-Adha commemorates the moment the prophet Ibrahim showed that he was willing to sacrifice his son Ishmael. Believers slaughter animals as a symbol of thanks to Allah for having spared Ishmael.

Nearly 100,000 animals were slaughtered across Dhaka this year, BBC Bengali said.
