The militants shouted “Allahu Akbar” before they attacked the law 
enforcers during a special drive of the joint forces in Dhaka’s 
Kalyanpur today.
Police found “Allahu Akbar” inscribed black flags from the den, Dhaka
 Metropolitan Police (DMP) Commissioner Asaduzzaman Mia said while 
addressing a press briefing at his office.
Nine militants were left dead during the raid and one was caught alive.
Police recovered 13 handmade grenades, one sword, one pistol, seven 
magazines and bullets from the den, the DMP commissioner said.
The militants had rented the apartment on June 20 and had gathered there to carry out terror attacks, he claimed.
One police man was slightly injured in the operation, Mia said.
The militants were aged about 20, wore jeans and sneakers and were highly educated, he added.
Mia further added that police suspect these attackers belong to the 
same group that attacked the Gulshan café because similar kind of red 
handkerchiefs and backpacks were found. “Black dresses were also found 
there,” he added.
The militant detained from the spot with bullet injuries was taken to
 Dhaka Medical College Hospital. He claimed to be a member of the 
Islamic State, DMCH police camp sources said earlier.
