"Groups from the observation posts of the radiation, chemical and biological protection units with special equipment stationed in Syria arrived to the area of shelling urgently. They work with the injured taken to medical institutions, monitor the situation in the area where the militants used poisonous substances," Konashenkov said.

The symptoms of those injured shows that most likely, the shells had been filled with chlorine, he added.

"According to preliminary confirmed data, in particular, by the symptoms of poisoned victims, the shells that were fired at residential areas of Aleppo had been filled with chlorine," the spokesman said.

Medical aid was provided to 73 civilians, including four children, after militants' attack with poison-filled shells in the Syrian city of Aleppo, doctor of the emergency department of a hospital in Aleppo, Shervan Sheho, told journalists on Sunday.

"According to updated data, 73 civilians, including four children, were given medical aid after Aleppo shelling. All hospitalized people have difficulty breathing and their eyes were watering. In medicine, this is called a gas allergy," Sheho said.

One of the eyewitnesses of the shelling, Ahmet Mohammed, told reporters that the victims did not immediately feel the first signs of poisoning.

"My brother was at home, he heard that shells were falling, but he thought that nothing terrible had happened. However, after two hours his condition worsened, it became difficult for him to breathe, the ambulance took him to a hospital," he said.

A resident of Nile Street in Aleppo, Galia Ali said that she was given first aid at the hospital, after which she was able to return home.

"But then my daughter's condition worsened, and my family brought her to the hospital," the woman added.

Gastelum, who is in opposition to the current Mexican government, has been vocal in his disdain for the federal authorities and has sided with US President Donald Trump. Gastelum stirred controversy after he was spotted wearing a red "Make Tujuana great again" cap, and invited an endorsement by the US President himself, who tweeted that like Tijuana, the US is "ill-prepared for this invasion."

While Gastelum has not been a popular figure among the Tijuanese, with his approval rating in single digits, many locals appear to support his anti-migrant stance. Last Sunday, dozens of protesters took to the city streets chanting "Tijuana first" and "Long Live Mexico."

One source of the residents' growing concern is the surging crime rate associated with the caravan migrants, who often lack proper accommodation, food and basic utilities.

The city authorities have released new data on Friday which states that 108 Central American migrants have been arrested so far, including 104 for administrative offenses, such as possession of drugs, public intoxication and disturbance. The remaining four are to be prosecuted for robbery, fights and insulting authorities.

Gastelum has recently drawn backlash and was forced to apologize for calling migrants "bums" and "pot smokers" preoccupied with nothing but disturbing the "tranquility and security of Tijuana."

The Prescription Drug Price Relief Act would force drug companies to price medicines equal to or below the median price of the same drug in five countries: Canada, the United Kingdom, France, Germany and Japan. This legislation would lower drug prices for all Americans. In addition, regardless of the price in other countries, anybody who feels that their medicine is excessively priced can petition the government to lower the price. Most importantly, if companies refuse to lower their prices, then the federal government would allow generic competition in order to lower the price.
