Internship gaps

Hello, i graduated from india in 2015. And i have doen my internship from march 2014 to june 2015 with a gap of 2months in between. This is 2 months gaps is due to strike we have done so entire batch didnt attend the internship in these 2months. As a result, we have done extension of 2months at the end. I am done with my plab1 and plab2. Right now i am worried about gmc registration. So if at all gmc asks me about the gap what should i say? How can i explain the strike we have done? Will it cause any trouble?
