( CNN ) -- Separate federal indictments claim that supporters of the Islamic extremist group Al-Shabaab have funneled money for brutal terrorist operations . In one case , two men were indicted in Missouri for allegedly funneling money to the Somali group , the Justice Department said Wednesday . The indictment said Mohamud Abdi Yusuf of St. Louis discussed Al-Shabaab in code language and used fictitious names and phone numbers to send money to the group 's supporters through remitting businesses in the United States . Yusuf is also charged with conspiring with Abdi Mahdi Hussein , an employee of a licensed remittance company , to structure financial transactions so as to avoid any record . Hussein was also indicted and arrested for conspiracy on those transactions . A third man , Duwayne Mohamed Diriye , is accused of helping distribute that money to Al-Shabaab from inside Somalia and Kenya . He has also been charged but remains at large in east Africa . FBI special agents arrested Yusuf in St. Louis on Monday and Hussein on Tuesday in Minneapolis , Minnesota , according to the Justice Department . Both men appeared in federal court Tuesday . If convicted , Yusuf faces a maximum of 15 years in prison and/or fines of up to $ 250,000 for each count of providing material support to terrorists . Yusuf and Hussein could each be sentenced to a maximum of five years in prison and/or fines of up to $ 250,000 for conspiring to structure transactions . The indictments were made public a day after three men in San Diego , California , were similarly charged with providing support to the al Qaeda-linked group . Issa Doreh and Mohamed Mohamed Mohamud , clad in orange jumpsuits , pleaded not guilty at a federal hearing in San Diego on Wednesday . A third man named in the indictment , Basaaly Saeed Moalin , was arrested Tuesday but was not in court . The five-count indictment alleges conspiracy to provide material support to terrorists , conspiracy to provide material support to a foreign terrorist organization , conspiracy to kill in a foreign country , money laundering and providing material support to terrorists . According to the indictment , the three provided thousands in funding for Al-Shabaab to purchase weapons , including rocket-propelled grenades and improvised explosive devices . Before his death in May 2008 , Al-Shabaab militant leader Aden Hashi Ayrow had called `` for foreign fighters to join Al-Shabaab in a 'holy war ' against the Ethiopian and other African forces in Somalia , '' the indictment states . The defendants , individually or together , funneled about $ 10,000 to Somalia , the indictment states , indicating that Ayrow told them , `` it is time to finance the jihad . '' Each rocket-propelled grenade cost $ 270 , an uncharged co-conspirator told them . A U.S. missile strike killed Ayrow . Dozens of supporters for the defendants , many in traditional Muslim garb , packed the small courtroom of U.S. Magistrate Judge William Gallo , who set a bail hearing for Friday morning . Assistant U.S. Attorney William Cole requested that the men be held without bail , alleging that they are flight risks and a danger to the community . Prosecutors would not discuss the nationalities of the defendants . Al-Shabaab has been waging a war against Somalia 's government in an effort to implement a stricter form of Islamic law , or sharia . Somalia has not had a stable government since 1991 , and fighting between the rebels and government troops has added to the impoverished east African nation 's humanitarian crisis . Just last week , Al-Shabaab publicly executed two teenage girls after accusing them of being spies for the Somali government , the group said . `` Those two girls were evil , and they were spies for the enemy [ the Somali government ] , but the mujahedeen caught them and after investigation , they admitted their crime , so they have been executed , '' said Sheikh Yusuf Ali Ugas , commander of Al-Shabaab in Beledweyne , a town in central Somalia . Al-Shabaab is one of almost 50 groups that have been designated by the State Department as foreign terrorist organizations . CNN 's Casey Wian contributed to this report .
