Two persons including an activist of Democratic Party (Nationalist) were injured in a militant grenade attack in summer capital Srinagar [ Images ] on Thursday afternoon.

The police said militants tossed a grenade at a headquarters of the Democratic Party headed by former minister Ghulam Hassan Mir at Rajbagh.

"Two persons including a party activist and a driver were injured in the explosion. The injured were taken to hospital," a senior police officer said.

They said Mir was not inside the party headquarters at the time of the attack this afternoon.

Mir, who was earlier a close confidante of People's Democratic Party patron Mufti Mohammad Sayeed, is contesting election from north Kashmir [ Images ] Gulmarg constituency that went to polls Sunday last.

He was expelled from the PDP last year. No group has yet claimed responsibility for the attack.
