Protestors and young students in Yemen are demanding justice for Joel Shrum, the American English teacher executed by terrorists this week in the city of Taiz.

Al Qaeda claimed responsibility for the killing, accusing Shrum of trying to convert Muslims.

Meanwhile, the people Shrum devoted his life to are demanding the murderers be caught and tried.

Hundreds of young protesters marched in honor of their teacher this week, holding posters that read "We Love You, Joel."

The young Yemenis said Shrum was gunned down in his car for no good reason. He had worked in the Islamic nation for the past two years, teaching poor people English and vocational skills.

"Mr. Joel came all the way from the United States of America, having nothing but good intentions to help and teach the people of Taiz. And I believe he did nothing to be killed for," one young student said in English, in a video of the protest posted on YouTube.

However, terrorists in the country claim Shrum was proselytizing, and had to be killed. On Mar. 18, two gunmen in military uniforms rode up alongside his car and opened fire, killing the 29-year-old on his way to work at the International Training & Development Centre. Shrum's killers remain at large.

"And I can say that he was kind, peaceful, loving, helping, and he was helping everybody at the Institute," the young protester said.

Shrum is survived by his wife and two young boys, who moved with him to Yemen in 2009.

"I just have one question for those terrorists. What did you achieve now? What is your goal now? Are you satisfied? Are you happy? Congratulations," one woman cried out on camera.

The United States has condemned the attack, calling it a "terrorist act."

Meanwhile, the Yemenis Shrum impacted are mourning the loss of their beloved teacher and friend.

"He came all the way and chose to live in Taiz because he loved Taiz and he loved the people of Taiz," the young man said in the video.

"He was there when we needed their help, and the pay off for that guy was to kill him in that heinous way," he said.

The Institute has since shut down while it assesses the security of its workers.
