Shell suspends operations in Nigeria

Shell has decided to suspend operations in Nigeria. According to a Shell top official, the reason for the suspension is due to five major militant attacks on Utorogu-UPS trunk line on January 7; the Amukpe-Rapele manifold attack of January 11; the Trans Escravos-Forcados River manifold attack of February 28; the Trans-Forcados pipeline (Chanomi Creek manifold) attack of June 12; and the militant attack on Trans Ramos pipeline on June 16.

I did a quick google news search but couldn't find any thing to collaborate this.
Does anyone know anything about this? Is Shell really shutting down all operations in Nigera?

There's this, from Nigerian paper "This Day":
