At least two people were killed in the second attack in three days on aid workers' housing, and authorities fear hostages may have been taken into the compound. At least two insurgents with suicide vests were also killed, one by his own explosives, while the other was shot, Qadam Shah Shaheem, an Afghan army commander, said, adding that eight people, including two foreigners, were rescued, but it was unclear how many attackers were still on upper floors. A Taliban spokesman said in a statement that its fighters had targeted a Christian organisation seeking to convert Muslims.
