Turkey strongly condemned terrorist attacks on public transport networks in London on Thursday.

"We express deep sorrow over casualties in the terrorist attacks," Turkish Foreign Ministry said in a statement.

"Turkey, which has suffered much from terrorism for years and which lost tens of thousands of its citizens due to terrorism, strongly condemns every kind of terrorism and these attacks (in London)," the statement said.

"These attacks have once more indicated the necessity to have decisive and efficient international cooperation in countering terrorism. We hope that the assailants of these inhumane attacks will be arrested, and stand before justice as soon as possible," added the statement.

Near simultaneous explosions rocked at least three London subway trains and ripped apart a double-decker bus at the morning rush hour Thursday, causing an undetermined number of deaths and injuring more than 300 people.
