Both sides appeared to step back on Wednesday after Iran launched a series of ballistic missiles at two military bases housing American troops in Iraq without causing any casualties.

No one was injured in the missile attack, which was in retaliation for the killing of Iranian Maj.-Gen. Qassem Soleimani by a U.S. drone last week.

The Canadian Forces have flown dozens of Canadian, American and other allied troops out of Iraq ahead of Iranian missile strikes on multiple military bases.

Iran wants to increase its missiles’ range, a senior military official was quoted as saying on Tuesday, a move that would irk the United States which views Tehran’s weapons program as a regional security threat.

Iran will continue missile tests to build up its defence and deterrence capabilities, a top military spokesman was quoted as saying on Sunday, following a U.S. allegation that Tehran had carried out a new missile test.

Iran's paramilitary Revolutionary Guard launched six ballistic missiles early Monday toward eastern Syria.

Iran has given ballistic missiles to Shi’ite proxies in Iraq and is developing the capacity to build more there, Iranian, Iraqi and Western sources said.

A Canadian man has been sentenced to 3 1/2 years in prison in the United States for conspiring to send restricted high-tech goods to Iran.
