 MEXICO CITY (Reuters) – Grappling with outrage over violence and impunity after the apparent massacre of 43 trainee teachers, Mexican President Enrique Pena Nieto on Tuesday accused unspecified groups of seeking to destabilise his government. 
  
 Protest marches over the crime, which the government has blamed on corrupt police in league with a drug gang and city officials, have overshadowed Pena Nieto’s efforts to boost years of sub-par economic growth via a raft of economic reforms. 
  
 The trainee teachers were abducted in late September by corrupt police working with a drug gang, and their remains were apparently incinerated. 
  
 Protests have yielded sporadic violence, with demonstrators setting fire to the doors of Pena Nieto’s ceremonial palace in central Mexico City, as well as torching or trashing regional government buildings and political party offices. 
  
 “Structural reforms and big changes have … without doubt affected interests of those who have much and of others who oppose our nation-building project,” Pena Nieto said. 
  
 “We have seen violent movements which hide behind the grief (over the missing students) to stage protests, the aim of which at times is unclear,” he added. “They seem to obey interests to generate instability, to foment social unrest.” 
  
 Pena Nieto is also on the back foot after the government angered China by revoking a $3.75 billion (2.39 billion pounds) high-speed train contract after opposition lawmakers claimed it was a stitch-up. 
  
 Compounding matters, it emerged that a Mexican group in the winning Chinese-led consortium owned a $7 million house that Pena Nieto’s wife was in the process of acquiring, raising questions about a possible conflict of interest in the bidding process. 
  
 Questions remain over the house. The government has not said how much first lady Angelica Rivera paid for it, nor why she was transferring funds directly to the firm that owned it. 
  
 As he set foot back in Mexico late on Saturday after a state visit to China, Pena Nieto was forced to address the house, saying he would clear up “imprecise and baseless assertions” on it. The government has yet do so. 
  
 On Tuesday, Pena Nieto said he had asked his wife to publicly explain how she came to acquire the property.

Mexico's attorney general had had about enough of questions over the murder of 43 students gruesomely burned in a 14-hour fire, and said as much on live television Friday. "Ya me canse," said Jesus Murillo Karam, a phrase translated variously as "Enough, I'm tired" and "I've had enough," in attempting to signal the end of an hour-long press conference. Mexicans, it turns out, have had about enough of nearly a decade of mind-numbing violence that has claimed the lives of about 100,000 of their countrymen—and they let Murillo Karam know it, reports the AP. Within hours, Murillo Karam was the not-so-proud inspiration behind #YaMeCanse and #estoycansado ("I'm tired"), reports Reuters. The Twitterverse had no shortage of remedies for Murillo Karam's exhaustion, most along the lines of "If you're tired, why don't you resign?", as well as an avalanche of tweeters' own versions: "Enough, I'm tired of living in a narco state" and "Enough, I'm tired of corrupt politicians" among them. And Mexicans' outrage over the massacre is proving explosive: Reuters notes that protesters also spray-painted "I've had enough ... of fear" outside Murillo Karam's office overnight even as thousands marched in protest nearby—many carrying #YaMeCanse signs—and violence broke out, with protesters breaking the National Palace's entrance doors and cars burning in Chilpancingo, the capital of Guerrero state, home to the murdered students. (The AP has video of protests here.) Others protesters are marching 112 miles from Iguala to Mexico City.
