Pakistan's military has expressed concern about the ongoing political and ethnic violence in the country's largest city, Karachi, where more than 200 people were killed in unrest last month alone.

During a meeting Monday in Rawalpindi, army chief General Ashfaq Parvez Kayani and other military commanders discussed the law and order situation in Karachi and its implications on the national economy.

The government has deployed additional police and paramilitary forces to the southern port city to try and quell the violence, which has escalated in recent months. Karachi, home to some 18 million people, is Pakistan's economic hub.

Authorities say the killings are part of clashes between the city's main political groups, which represent two different ethnic communities. The political parties are also said to have links to armed criminal gangs.

In a statement Monday, Pakistan's military said it expected that measures recently taken by the government to help quell the unrest would help remedy the situation.

Meanwhile, in the country's northwest, local officials say a military vehicle hit a roadside bomb in the South Waziristan tribal region late Sunday. At least 10 soldiers were wounded in the attack.
