Indian celebrities, including Shruti Haasan, Neha Dhupia, Anubhav Sinha and Salim Merchant, were shocked and disturbed with the news of terror attacks in London. They have urged the people to stay calm and united.

Six people were killed and 48 others injured in two terror strikes in London in which three male attackers were shot dead by the police. The attack began on London Bridge when a white Transit-style van drove into a crowd of people on Saturday. This is the third terror attack in the UK since March. 

Here's what the stars tweeted:
