Taliban attacks have left 19 dead during a spate of violence targeting security forces across Pakistan.

A suicide bombing, an improvised explosive device explosion and a drive-by shooting claimed by different Taliban groups targetting soldiers, police and media workers within a span of 24 hours show new coordination by the militants.

A Taliban suicide bomber blew himself up amid security forces escorting a rally in eastern Pakistan on Monday, killing 13 people and wounding scores more in the deadliest attack.

The bomber targeted a rally of drugs manufacturers protesting a new government law in the city of Lahore, said Mushtaq Sukhera, police chief of the province of Punjab.

Investigators have found the remains of the body of the suicide bomber, who is said to be in his 20s, the provincial forensic agency said.

Jamaat-ul-Ahrar, a splinter group of the Pakistani Taliban, claimed responsibility for the bombing in an email to media.

"It is the beginning of a new operation against security forces in Pakistan," the group's spokesman, Asad Mansour, said.

Television footage showed people running in panic and wailing in grief outside hospitals to find out about their loved ones after the bombing.

Hours later, two officials of a bomb disposal squad died while defusing a roadside device in the south-western city of Quetta, police official Ali Asghar said.

Overnight, an improvised explosive device planted by the Taliban injured three Pakistani soldiers, who succumbed to their wounds on Monday, a military's statement said.

Taliban gunmen on motorbikes also gunned down a cameraman for a local television channel in another assault on media, which drew an outcry from local and global journalists' bodies.
