Afghan President Orders Security Review in Kabul

Meanwhile, Afghan security forces are on high alert.  They have tightened security in Kabul and are searching vehicles as they enter the city. 

Deputy Police Chief Mohammad Khalil Dastyar said troops also increased the number of checkpoints in the city, along with both foot and vehicle patrols. 

Afghan intelligence service chief Amrullah Saleh said seven attackers carrying automatic weapons and wearing suicide vests struck during morning rush hour Monday, triggering fierce gun battles with police.  

At least three security force members and one child are among those killed. Investigators say the seven attackers were killed in clashes with law enforcement officials. 

Officials say the attackers' plan was to try to seize key ministries and to storm the presidential palace, but that they failed to do so.

Officials say President Karzai was swearing in new members of his Cabinet when the violence broke out.
