Problem:The vandalism acts at the two mosques are two of several incidents over the last two weeks that are being investigated as hate crimes, possibly as retribution for the Dec. 2 attack on the Inland Regional Center in San Bernardino. That rampage, which killed 14, was carried out by a pair of shooters who were apparently inspired by Islamic extremism. The shooters died in a showdown with police hours later. ||||| (CNN) One mosque had "Jesus is the Way" spray-painted across the front. Another mosque was defaced and left with a fake grenade in the driveway. 
  
 Both acts of vandalism took place in the same California city, about an hour west of where the San Bernardino terror attack took place this month. 
  
 And Hawthorne police said both incidents are now classified as hate crimes. 
  
 Early Sunday morning, Hawthorne police received a call about vandalism and a possible explosive device in front of the Ahmadiyya Muslim Community Baitus-Salaam Mosque, the Police Department said. 
  
 When officers arrived, they found what looked like a grenade and evacuated the area. But the object turned out to be a fake plastic grenade. 
  
 Someone had also spray-painted "Jesus" across the mosque's fence. 
  
 The same day, another mosque -- the Islamic Center of Hawthorne -- was found vandalized, with "Jesus is the Way" spray-painted on the front of the building.

 Hawthorne police believe both crimes took place overnight. 
  
 The FBI and the Los Angeles County Sheriff's Department are working with Hawthorne police in the investigation.

 "All evidence will be reviewed by state and federal prosecutors to determine whether a violation under federal civil rights statutes occurred. The FBI is committed to ensure law-abiding citizens are protected and to deter those who would threaten them." 
  
 Hawthorne police said that after the San Bernardino attack, the department has communicating more closely with local Islamic centers. 
  
 "The Department will continue to closely support our faith-based partners and work to assure the safety of its members," Hawthorne police said. |||||
Solution:
In what the FBI and local police are treating as a hate crime, two California mosques in the same city were vandalized with pro-Christian graffiti over the weekend. On Sunday morning, "Jesus Is the Way" was found painted on the front of one mosque in Hawthorne, and the word "Jesus" was on the fence of another, where police found a grenade that turned out to be fake, the Los Angeles Times reports. Police in Hawthorne, which is about an hour away from San Bernardino, say they've been communicating more closely with Islamic centers since the massacre and are working with the FBI and the LA County Sheriff's Department on this investigation, reports CNN. Last week, a Coachella mosque was set on fire and a pig's head was dumped in front of a Philadelphia mosque amid what Council on American-Islamic Relations spokesman Ibrahim Hooper tells the New York Times was an "unprecedented spike in anti-Muslim incidents" after the attacks in Paris and San Bernardino. He blames the surge on heated rhetoric from Donald Trump and others. "Right after 9/11, anti-Muslim hate was on the fringes of society, and now it has been brought right into the mainstream," Hooper says. "It's almost acceptable now to hate Islam and Muslims, and now we see the results." (A Texas group posted the addresses of Muslims and people it labeled "Muslim sympathizers.")
