KARACHI: A hand-grenade blast near Karachi's Hassan Square area on Wednesday injured two policemen while another explosive device detonated near Tipu Sultan police station causing fear and panic to grip the locality, DawnNews reported.

Unknown attackers hurled a hand-grenade at a police mobile van near Hassan Square flyover in Gushan-i-Iqbal area of Karachi. Two policemen were wounded in the incident, and were shifted to a nearby hospital for treatment.

The attackers managed to flee from the scene.

In another incident, unknown persons threw some explosives near Tipu Sultan police station. The explosion caused fear and panic to grip the surrounding areas.

However, there was no loss of life or property reported in the incident.

Earlier during the day, a bomb shell was discovered in a garbage heap in Baldia Town, Sector 9 area of Karachi.

The Bomb Disposal Squad later arrived at the site and took the shell into their custody after examining it.

This is not the first attack on Police and Rangers personnel in the Sindh capital as many have lost lives and sustained serious injuries in fight against militancy, targeted killing and sectarian violence in the past as well. Grenades have been lobbed at police stations and vehicles.

SSP Farooq Awan escaped a bomb attack on him last week that killed two passersby and injured at least six others. However, SP Chaudhry Aslam could not do so and along with his two colleagues was killed in a Taliban bombing in January.

In February, the Tehrik-i-Taliban Pakistan (TTP) had claimed responsibility for an explosion targeting a police bus near Razzaqabad police training college in Karachi's Shah Latif Town in which 13 policemen were killed and 47 others injured.

But, the Pakistani Taliban are not the only driver of the violence in the city.

Karachi has been a cauldron of ethnic and political tension for decades, where political parties have militant wings, gangs make money through drug-trafficking, land grabbing and other forms of crime, and sectarian violence.

Targeted operations by Police and Rangers’ forces are ongoing in the city under a directive issued by the federal government against criminals already identified by federal, military and civilian agencies.
