Deadly explosion hits Tehran clinic

At least 19 people have been killed and several more injured in an explosion at a clinic in Iran's capital Tehran, officials say, adding the death toll may rise further.

Iran's state media quoted senior officials as saying the blast at the Sina Athar clinic was caused by a gas leak.

Television pictures showed plumes of smoke billowing in the sky. Firefighters extinguished the blaze several hours later.

Most of the victims of Tuesday's blast were women, according to the authorities.

Some of the victims "were in upper floors, in operation rooms - who were either patients being operated on or those with them", Tehran fire department spokesman Jalal Maleki was quoted as saying by state media.

"They, unfortunately, lost their lives due to the heat and thick smoke," he said, adding that firefighters had rescued 20 people.

The clinic, which carries out light surgeries and medical imaging, had 25 employees inside at the time of the explosion, Mr Maleki said.

The incident comes several days after a big explosion near a military facility rocked Tehran.

The cause of that incident was also said by the authorities to have been a gas leak.
