A battle between Pakistani security forces and less than a dozen gunmen is underway at the VIP terminal of the Karachi's Jinnah International Airport. According to reports, at least five people have been killed.

The attack started late Sunday evening and has carried on into the morning with reports of several explosions from both media on the ground as well as passengers who are stuck onboard planes at the airport.

So far no one has taken responsibility for the attack although many are pointing fingers at the Pakistani Taliban, which recently ended a ceasefire it held with the government. 

There are also reports that the gunmen are wearing suicide belts:

For some context, recent trouble in Karachi was singled out by Foreign Policy earlier this week with the ominously-titled piece "Will Karachi Become the Next Waziristan?"

Pakistan's cities are suffering from relentless, and in some cases unprecedented, levels of violence. In 2013, Karachi's terrorist violence increased by 90 percent. The city's 2,700 casualties from violence that year represented a new record."

In the past decade, cities in Pakistan have grown at a massive clip, driven by an influx of people seeking better economic opportunities and, more importantly, to avoid the conflict currently happening in the rural parts of the country.

Elsewhere, on the Pakistani-Iranian border, a gun and suicide bomb attack has reportedly killed nearly two dozen people, many of whom were reportedly Shiite pilgrims. Akbar Durrani, home secretary of Pakistan's southwest Baluchistan province, told the AFP:

“Four attackers including two gunmen and two suicide bombers attacked the restaurant in Taftan.”
