4 Pakistani soldiers killed by blast

Four Pakistani soldiers were killed and five others injured in an IED blast in the lawless North Waziristan tribal region today.
The Improvised Explosive Device was planted by the roadside and detonated as a security forces' convoy was passing through the area, military sources said.
Security forces cordoned off the area and launched a search operation. No other details were immediately available.
No group claimed responsibility for the attack. US and Afghan officials described North Waziristan Agency as a safe haven for Taliban and Al Qaeda elements.
