One of the largest ports in south Asia was closed after two cargo ships collided at the Karachi harbour, spilling shipping containers into the sea.
The collision was captured on film by a dock worker, and video showed a Hapag-Lloyd ship, the Tolten, clipping a stationary ship while pulling into port in the Pakistan capital.
The footage showed containers bobbing around the harbour, while another sank.
At least 21 shipping containers fell into the sea, and contained cars and other freight, according to Pakistan's Geo News.
The incident reportedly damaged the berth and the stationary Hamburg Bay, also owned by Hapag-Lloyd.
The port will reopen once the containers have been recovered.
According to a statement to Port Technology, Hapag-Lloyd said they regretted the incident and would investigate how it happened.
"We have ascertained on-site that no-one was injured as a result of the incident, and that there has been absolutely no environmental pollution," the statement said.
"There is yet to be a definitive explanation for this incident."
