U.S. President Donald Trump will visit El Paso on Wednesday, Mayor Dee Margo told reporters on Monday.

The death toll from weekend mass shooting in El Paso, U.S. state of Texas, has risen to 22 after two people died at a hospital, El Paso police and medical officials said on Monday. One victim died on Sunday night, and another died on Monday morning.

Trump said on Monday morning the shooter's manifesto was "consumed with racist hate."

He called for mental health gun control reforms, death penalty for those who commit mass murders and more bi-partisan cooperation over gun laws.

On Sunday, Trump issued a proclamation, ordering that all American flags at military installations, federal facilities, and the White House be flown at half-staff until sunset on August 8.

Mexican Foreign Minister Marcelo Ebrard said on Sunday that the attorney general would consider litigation claiming that terrorism was committed against Mexicans in a shooting in El Paso, Texas, in which 20 people were killed, including six Mexicans.

Ebrard said that such an act could lead to the extradition of the person responsible for the shooting. "For Mexico, this individual is a terrorist," he told a news conference.

Ebrard also called the shooting "a terrorist act" against Mexicans and urged the U.S. government to "set a clear position against hate crimes."

Mexican President Andres Manuel Lopez Obrador said six Mexicans were among the 20 killed in the attack on Saturday in the border city, and seven more were wounded.

The suspected gunman, 21-year-old Patrick Wood Crusius, was from a Dallas suburb more than 900 kilometers from where Saturday's shooting unfolded.

Crusius has been charged with murder offenses that can carry the death penalty, police said Sunday.
