At least 30 people were killed and 40 others injured in a suicide blast which took place Monday afternoon near a mosque in Wana of South Waziristan in northwest Pakistan, reported local media Express.

According to the report, the blast took place near a mosque where there were reportedly more than 100 people offering prayers inside. Some reports said that the blast took place inside the mosque.

This is the third blast reported Monday in Pakistan.

Earlier Monday, a minor blast took place in Pakistan's northwest Khyber tribal agency, injuring seven security troops near a mosque in Bara. This was shortly followed by a remote- controlled explosion in adjoining Kurram tribal agency, killing at least eight people and injuring several others.

The second blast took place in Khomta, a central town in Kurram, when a tribal meeting was being held to resolve dispute over primary school issue.
