President Donald Trump reaffirmed his demand for the long-promised wall on the Southern border of the U.S. after terrorists killed at least 235 people in Egypt.

“With so much loss of life. We have to get TOUGHER AND SMARTER than ever before, and we will,” Trump wrote on Twitter. “Need the WALL, need the BAN! God bless the people of Egypt.”

Will be calling the President of Egypt in a short while to discuss the tragic terrorist attack, with so much loss of life. We have to get TOUGHER AND SMARTER than ever before, and we will. Need the WALL, need the BAN! God bless the people of Egypt. — Donald J. Trump (@realDonaldTrump) November 24, 2017

The president announced plans to speak with Egyptian president Abdel Fattah el-Sisi on Twitter.

According to the New York Times, the attack took place at a mosque where most of the victims were Sufi Muslims — considered heretical by extremist Muslims.

Terrorists triggered a bomb inside the mosque and sent gunmen to shoot people as they fled the scene.

In recent days, Trump has repeatedly stressed the need to build the wall, including on Twitter on Thanksgiving Day and after a border guard was was reportedly killed by illegal immigrants.
