On Friday, Nov. 24, terrorists attacked a mosque in Egypt’s North Sinai region, killing at least 305 and injuring another 128 people, according to CNN.

CNN reported attackers used at least two improvised explosive devices to start the attack on the mosque right as midday prayers were about to begin.

According to the Guardian, while people ran out of the mosque, gunmen waited outside on four off-road vehicles and opened fire on the fleeing worshipers.

Reuters reported the gunman also shot the ambulances as they came in to help the wounded.

CNN reported this attack is the deadliest to take place on the Sinai Peninsula. According to Vox, no one has taken credit for this attack at this time, but the assailants carried ISIS flags.

The mosque that was attacked is part of the Sufi branch of Islam. According to CNN, Sufism is a mystical branch of Islam that some Muslims consider heretical.

According to The New York Times, the Egyptian military carried out airstrikes at the fleeing attackers. NBCNews reported the Egyptian government declared three days of mourning soon after the attack. The President of Egypt, Abdel-Fattah el-Sisi, held an emergency security meeting with his security officials.

World leaders condemned the attack, BBC reported. UK Prime Minister Theresa May tweeted she was appalled by the attacks and offered her condolences, and French Foreign Minister Jean-Yves Le Drian offered her condolences to the families of those killed in the “despicable attack”.

According to CNN, Palestinian Authority President Mahmoud Abbas said in a statement,”We stand with Egyptians in their war against terrorism and against anyone who tries to harm the Egyptian national security.”

President Trump went to Twitter to condemn the attack calling it cowardly and for the end of terrorism through military methods.

Erika Robinson, a junior studying Elementary Education, reacted to the bombing by saying the attack was awful.

“I don’t understand why people are so terrible sometimes,” said Robinson.

While Robinson does not see a way to physically help the victims of the attack, there was something else she and others could do.

“As individuals the best thing we can do is pray for those affected by (the attack),” Robinson said.
